What's your weirdest nausea trigger?

Mine is walking. Yes, walking. Isn't that strange? I take the bus to work, and ironically, that doesn't bother me. In fact, I can even read on the bus - something that would normally make me sick - and it doesn't seem to bother me. But the second I step off the bus? It takes every ounce in me not to yak on the street.

Oh, and also, the shower. I have puked nearly every morning in the shower. I think part of that is my empty stomach, but still...

Anyone else have totally bizarre nausea triggers?
