Q: Why did the rooster cross the road?
A: To show he wasn't a chicken.
Listen up, buttercup. This joke is funny 'cause it's a play on words. You see, the rooster crossed the road to prove he ain't chicken, like, not brave. It's funny because you thought a rooster would cross the road to get to the other side, but roosters always gotta be different. As you know, the 'chicken' is also a fowl! Wow. You're a smartie now.
