Dinosaur Crosses the Road

Alright listen up, you probably don't know a lot about jokes but Explain Bear is here to learn ya! You see, the joke is funny because it makes you think about why something crosses the road. Usually, it's to get to the other side but dinosaurs and chickens didn't live at the same time! Dinosaurs were gone way before chickens came along. Did you know you are more likely to be killed by a cow than a shark? Ok bye!
