Explain Bear
Listen up, chucklehead. The chicken crossed the road to get to the "idiot's" house. Then, when the idiot answers the door, the joke reveals that *you* are the idiot, because the chicken is at *your* door. Congrats, you played yourself. Also, fun fact, you probably eat a lot of dino nuggies.
