As for April Fools, I did perpetuate one effective trick (poisson d'Avril!). I emailed B the following (Subject: Don't Get Mad):
So we went to the farmer's market this morning, and the Milo Foundation was there, and there were these super-cute cats, and the kids really wanted one, so we adopted a cat. I know you will be pissed but this is a super-cute cat. We are still discussing a names. Names proposed include Pat, Tory, Destu and Strug.Probably because he was at the tail end of a 48-hour bachelor party, he completely bought this. When he called to talk about it, I shouted, "Don't carry the cat around like that!" but I accidentally muted the phone with my jaw (a strangely common problem I have) and then lost steam on the joke. I don't think I've ever successfully tricked someone on April 1, and unless he's as sensorily-compromised next year, I doubt it will happen again.
