A-corny joke.
Because they are both surrounded by nuts.
Nothing. Because owls don't talk. Then it ate the squirrel, because owls are birds of prey.
I see frozen peas are cool this time of year. ..you might say that's a corny joke, but it's really not. It's a pea joke.
Thought of this one on my own while playing WoW a couple days ago and I'm pretty sure it hasn't been told before. I like corny jokes. I Googled it and didn't find anything (:
