Your best/Funniest/most memorable Sims moment

There was this thing that cracked me up today. I have a guy who's in a poly relationship (cheated the player-trait), one girlfriend, one boyfriend. Both of them were at his house and I decided that he and his boyfriend would woohoo. The guy's sister and the girlfriend were both in the room with his bed, so he naturally went "shoo, shoo". Only his sister left. The girlfriend just stood there, looking at them, grinning the whole time when the guys had fun in bed. After it he was going to woohoo with his girlfriend. The same thing happened - boyfriend stood there, actually walking to the bed, smiling, looking. I thought someone would get an embarrassed moodlet but oh no, not at all. When the guy and the girl went out of bed the boyfriend autonomously gave him a passionate kiss... while the girlfriend cheered and clapped her hands with a little thought bubble with her boyfriend's boyfriend in it. I was all "oooohhhh, you diiiirty devils!"
