and I don't know why. I just saw the episode last night where Mr. Pewterschmidt tries to destroy a park bench with an excavator and it just worked. I was crying laughing, I couldn't breath at times.
I never know when some odd/weird scene on this will crack me up.
I had the same experience when Brian found out Ida was a transexual AFTER he'd slept with her. His vomiting scene had me laughing so hard, I was crying. When Stewie had to back up because the vomit was getting closer to him - I lost it completely! That is one of my favorite episodes. Brian's final line to Quagmire "Hey Quagmire.....I BEEEEEEEPED your dad!" was hysterical.
There's also an American Dad episode that kills me too - it's the one where Steve kills Santa Claus and Santa and his elves/reindeer, et al., declare war on the Smith family. Before the skirmish, when Jeff arrives, they're getting ready to play some music with homemade instruments and Steve tells Bob-Todd that Jeff doesn't have an instrument to play. Bob-Todd tells him he can play the skin flute. Steve laughs, then Bob-Todd shows him the flute. Like you said, you never know when a scene will crack you up.
The first time I saw the living room contest to see who could hold off vomiting the longest after taking ipecac, I laughed so hard I had tears streaming down my face. I still lmao when I see it.
