Wyatt is the father of Penny, Randall and another daughter and the husband of Susan. He first appeared in "The Boyfriend Complexity".

Character Information

Wyatt is a very caring, friendly and fatherly person, who wants Penny to make both good decisions, but also to make his little girl happy. Penny mentioned her father at least twice before he appeared on the show.

According to Penny in "The Maternal Capacitance" (S2E15), Wyatt originally wanted a boy, but got her instead. He called her "slugger" until she got her first training bra, at which point he also stopped playing catch with her.

In "The Maternal Congruence" (S3E11), Penny mentions that Wyatt sent her a catcher's glove and a baseball for Christmas. When he learned that Penny was seeing Leonard, he was overjoyed, having met her moron ex-boyfriends. He was actually devastated at learning that they had broken up.

In "The Boyfriend Complexity" (S4E09), Wyatt is first seen in person. He comes to visit Penny, who claims, in order to get him off her back, that she and Leonard have got back together. As the episode progresses, the two carry on the ruse until Penny admits the truth to him. He is at first hurt that she felt a need to lie to him, but forgives her. When she is gone, Wyatt literally begs Leonard not to give up on her, as he is the best {{w|boyfriend}] she's ever had. He pretends to angrily throw Leonard out of the apartment as reverse psychology to get Penny's interest in him up. Leonard leaves, telling Wyatt that he will Friend him on Facebook.


Wyatt yelling at the couple.

In "The Hesitation Ramification" (S7E12), Penny has a phone call with her father after it is found that her role in "NCIS" is cut when aired. Penny tells Wyatt that her part wasn't cut because she was too pretty. He also doesn't need to come to Los Angeles to kick Mark Harmon's ass. Wyatt does not appear on screen in this episode, nor is he heard.

In "The Bachelor Party Corrosion", Penny calls her dad to tell him that she got married to Leonard. First he asks if she is happy, which she is. He is a bit perturbed since she waited a week to tell him, but is understanding and supportive and tells her that he his happy for her since she is happy; however, this may be because having a secret of his own, having accidentally ran over her pet pig, Moondance - almost a year ago. 


Penny escorted by the proud Wyatt.

In "The Conjugal Conjecture", Wyatt comes to Pasadena with his wife Susan and their son Randall for Leonard and Penny's wedding. He tries to balance the tension between his wife and son, the latter who has formerly been on parole. He has a close relationship with Penny, but his wife thinks he isn't strict enough with Randall. He also drinks quite often, much to Susan's discomfort, although Penny drinks more than he does and he and his daughter clink bottles. He is glad to meet Leonard's mother Beverly, the woman who raised the fine young man Leonard (but apparently unaware, forgetting or unintentionally neglecting the fact that Leonard is not pleased of how she raised him) and Wyatt is also looking forward to meeting Leonard's father Alfred. At the wedding ceremony, Wyatt proudly escorts Penny down the aisle and advises Leonard not to lend Randall any money.




Wyatt loves his daughter a lot, but Penny had some issues with him when she was growing up since he was raising her like a boy and calling her "Slugger".


Wyatt and Susan are obviously happily married and so they are a good couple. Although during Susan's first appearance, things are a bit tense between them about Randall's drug actions and his ending up in jail.

Penny's Siblings

Wyatt's relationship with his two other children, Penny's brother Randall and their sister is not known but it's obvious he loves them very much. He may not have been strict enough with his son that ended up in prison. His other daughter's water broke while they were dancing at her wedding.

Leonard Hofstadter

Wyatt is very fond of Leonard. He sees him as the first smart boyfriend Penny has dated. While all her other boyfriends are whom Wyatt considers to be losers, Leonard is seen by Wyatt as a friendly, caring person and a successful accomplished academic. During the time spent together, he happily reminisces about Penny's much stupider boyfriends, remarking that Leonard is a keeper. The two are also seen doing many activities together, both of them rather fond with spending time with each other. Along with this, he also pleads with Leonard to never give up on her. He was happy to hear that they got married and looked very proud escorting Penny down the aisle at their wedding redo.

The rest of the gang

Wyatt never met any of Penny and Leonard's friends yet who are members of the gang until "The Conjugal Conjecture" where he was with them at Leonard and Penny's re-wedding, but didn't speak to anyone. Although during the ride to the airport, Wyatt says that Sheldon reminds him of a turkey Penny and her family had who drowned looking up at the rain.
