Aardvarks don't have trunks!
Irrelephant.
Look out for the mice!
Because pepper makes them sneeze
Because everyone that can run, jump or swim is in the US.
Because they couldn't hold their trunks up!
Lock them both in the trunk of the car for an hour, then open it up and see which one of them is happier to see you.
A paredvark!
Because they always have their noses in other people's business!
