In a recent episode of "Young Sheldon," George's comment indirectly criticizes Penny's past in "The Big Bang Theory." While Sheldon's father never appeared in the show, a remark made by George suggests a subtle dig at Penny. In "The Big Bang Theory," Penny was initially portrayed as a stereotypical blonde bombshell who becomes friends with Sheldon and Leonard. The show often sexualized her character for cheap laughs and perpetuated misogynistic humor.

Penny gained a reputation for sleeping around early on in the series, and one episode featured a flashback of her nonchalantly taking a pregnancy test, implying she had experience with such situations.

In the conversation between George and Georgie in "Young Sheldon," George references girls who like to sleep around while discussing the possibility of Georgie being the father of Mandy's baby. This suggests that George sees Penny as the type of girl who may have been involved with multiple men.

"The Big Bang Theory" has faced criticism for its problematic humor, particularly in its earlier seasons. The show frequently used misogynistic comments from Sheldon towards Penny for comedic effect. However, as the seasons progressed and Kaley Cuoco had more input into her character's development, there was a noticeable change in how Penny was depicted.

Fortunately, "Young Sheldon" takes a more cautious approach to its comedy, as it is more of a family dramedy than a traditional sitcom. It avoids shaming characters like Mandy for getting pregnant and acknowledges that Georgie also shares responsibility in the situation. The show has become CBS' top comedy and has the potential to grow its fanbase with upcoming seasons. It also has the opportunity to improve in terms of quality and the type of humor it employs.

Overall, George's comment in "Young Sheldon" indirectly criticizes the portrayal of Penny's character in "The Big Bang Theory" and highlights the need for more respectful and inclusive humor in television shows.
