The interaction between Sheldon and Penny has been praised by critics. James Chamberlain of IGN wrote: "Cuoco and Parsons are great in their own right, but when put together, they truly shine." Matt Roush of TV Guide said that Sheldon and Penny's "scenes and episodes together are usually Big Bang at its best." Todd WanDerVerff of The A.V. Club wrote that they "made such an inspired odd coupling that at times, it seemed as though the entire show were about them" and their chemistry "has some of the rattle and rhythm of the great comedic duos".

The Shenny fandom was at its strongest during Season 1-4. The group became so large that fans set-up their own forum on Livejournal's Paradox. Founded on 23 July 2008, Paradox members followed the show for a number of years. Later, a website dedicated to Sheldon and Penny was founded called

The most notable Sheldon and Penny episodes appear in the earlier seasons. Sheldon analytical mind versus Penny's down-to-earth heart, clashed wonderfully from the very start. Much loved Sheldon and Penny episodes include:


Penny rubbing Sheldon's chest.

Season one's "The Pancake Batter Anomaly" features Penny playing nursemaid to Sheldon when he gets sick. Exposing for the first time, how a biological frailty as simple as the common cold, renders Sheldon beyond useless. His lack of awareness is at its peak and Penny's reluctant compulsion to help, coupled with the increasing intimacy of his requests, is what makes this a Shenny favorite. It's also the first time we hear them sing Soft Kitty.

In "The Barbarian Sublimation", Penny becomes addicted to Age of Conan online game and Sheldon becomes her mentor. Howard and Raj remark on the strangest of this union. "Like if Hulk were dating Peppermint Patty." One of the few episodes that is about Penny herself and not simply a romantic interest.

In "The Panty Piñata Polarization", it shows these two are evenly matched and also incredibly funny. Penny refuses to back down when Sheldon imposes a ban from their apartment.

"The Bath Item Gift Hypothesis" is arguably one of Big Bang's most famous moments for them. Sheldon delivers his first show of real human intimacy when his plan to match her Christmas gift giving fails when Penny gives him a present which emotionally floors him.

"The Adhesive Duck Deficiency" was the episode that really rocked the boat and brought the Shenny fandom to life. Sheldon is forced to help Penny get to hospital after she dislocates her shoulder in the shower. After this episode, aired the media picked up on the Shenny buzz and the fandom exploded. Later that season Sheldon was introduced to his now girlfriend Amy leading to much speculation about the timing within the Shenny community.

Later episodes have a different dynamic, focusing more on a bond between them rather than the opposites trope. Penny proves how she can take care of Sheldon, like his whisperer. Whenever Sheldon fights with anxiety or depression, Penny has her way of calming him down and showing him a way forward.

In the context of the series, they have been said to have a relationship who's closeness even bothers Amy per "The Viewing Party Combustion". Amy's questions confirm the Shenny relationship, admitting that Penny always comforts Sheldon when he's upset and she's the only one who can make him take his medicine, when he's sick. A level of trust that spans from "The Pancake Batter Anomaly" episode. When Leonard and Penny are arguing, Leonard mentions the weird relationship she has with Sheldon which she denies. But the Shenny relationship for fans of a romantic bond is purely hypothetical and doesn't necessarily rely on canon, even though they are portrayed almost like brother and sister.

Shenny has a fantasy sequence about an alternative reality where Penny attempts to seduce Sheldon in the Laundry room. However, this only exists in Amy's mind as she considers the "what ifs" possible if she and Sheldon had never met Leonard.
