youre right about it being unfunny it reminds me of when i was years old doing madlibs with my friends and filling in fuck for every word just substitute nigger in and you have this bit in a nutshell i remember watching gilbert laugh like that at one of arties jokes a while ago and then i realized artie totally botched the punchline he was trying to make some obscure reference which wouldve been funny but he botched the persons name and theres no way gilbert knew what artie was talking about gilbert still erupts with laughter gilbert just knows how to get on arties good side laugh at everything he says
