Why the Cow Laughed

Mich and I were discussing about whether I should buy a new frying pan or not when this came up.

Mich: Why don't you buy a simple one first?
Me: No. Want to do it must do it right. You don't use a butter knife to kill a cow right?
Mich: Huh?!
Me: Ya. You at least use a steak knife. If you use a butter knife, the cow will probably just laugh at you. Squirt a little bit of milk at you maybe. But if you use a steak knife then it's a different story.
Mich: .......
Mich: Baby....
Me: Ya? :D
