I am one of the older nerds at work, but nerd interests don't seem to stray too far. There was a surge of interest in Magic cards not too long ago. I took the cards in but haven't yet had the time to face anyone in a game. (Mind you, the goblin desk is still looking good)
Anyway, occasionally there is an amusing link send around. Here are two that amused me...
19th Century vampire hunting kit
and an amusing Chinese sign... (DV don't look)
