Dumb family jokes are the best.

Mine from our family road trip in a noisy car

Dad: the thing to do (for raising chickens) would be to buy eggs.
Daughter (thinking he said “pigs” not eggs): Yuck, then you’d have to slaughter them.
Dad: who slaughters eggs?
Daughter: anyone who wants bacon
Mom: I think we have a communication problem in this car
Son: Something wrong with the car mom?

It can’t be much dumber than that, right?
