Sitcoms usually generate humor through creating situations (hence the name) and it's been classically so that they don't usually feature heavy topics, strong language or sensitive themes. Shows like Seinfeld have ignored this successfully but most shows (Big Bang Theory included) have stuck to that formula more or less, which is why this episode stands out so much from Big Bang Theory episodes ever, and generally from a typical sitcom show.

Without spoiling anything, This episode features one of Sheldon's classic moments, where, without realizing the plethora lines that he is crossing, crosses them all, which makes for some hilarious super politically incorrect moments. The real mastery of the writing here is, that firstly, it's not so awful that anyone can justifiably be offended by it, but also the hilarity of the fact that the person being politically way incorrect isn't even aware of it.

This is definitely an episode you should watch if you think Big Bang Theory is not funny anymore. I think It continues to be one of the best shows ever and this episode is a tiny reason why.
