whenever i drive by a place that has cows, i always wonder if it is safe to ride them
WHO HERE HAS RIDDEN A COW?!
I've never ridden a cow, but I've seriously considered teaching our heifer to let us ride her.
Bulls can kill you!
True, but lot of animals can kill you. In general, a well treated bull is a nice old guy that is more gentle than the cows. I've seen and been around quite a few, and they're pretty nice. There is always the exception, and that exception is the example people take and use to say "Bulls are mean!". Sort of like with roosters; some attack, a lot don't, therefore roosters are bad.

I need ducks!!! Now!!!
