A perfect Sunny episode. First, let's review the scenes that made me laugh;
The funniest scene I think was the scene where Frank was playing against a kid with charlie standing next to himi openly talking to his talkie and buzzer in his pocket buzzing loud as hell and they do absolutely nothing to cover things up. It reminded me of another scene I really liked where Charlie was in Mac and Dennis's house and he was talking with Frank on his talkie and he would say stuff like "roger that" and Frank's voice was so loud you were kinda able to hear him through Charlie's earphones. That was hilarious to me and that chess scene felt like an improved version of that, not trying to cover up a plan that should've been secret.
I also liked that they can joke about gay people again, mac's plot was good in this episode it didn't feel weird but I do think, just like in the first episode of the season, they make mac look extra stupid for some reason, he wasn't always like that idk why they changed him so much he almost feels like a different character at this point.
Something I didn't like much was the SINNED scene, it was pretty funny but I think it was kinda unrelated to the whole episode and they gave it a little too much time. Instead of that scene we could've watch how they drugged Frank and did the operation.
So other than couple of small details, episode was fire. A must-watch!
