I can understand why an Uncle would be in there.
Someone who solves a problem you didn't know you had in a way you don't understand.
Cat you understand!
Because all of his uncles were ants!
The man replies: it's back there, I'm just going to get the water! (This is a true story, my uncle really said this)
Girl: My Aunt Boy: No it's an elephant. Girl: You obviously haven't met my Aunt
Because his uncles are aunts.
