Hummingbird.  These buggers are fast, and if you get too close to the feeder, they dive bomb your head.  Careful.

Bees.  Once I stepped on a bee.  That wasn't fun.  Another time I was opening a door and a bee stung my ring finger.  That wasn't fun either.  I still like them, though.

My cousins and I used to have a grasshopper catching contest.  They always won because I thought they were gross and did cartwheels instead.
