The Couple

I think that it can be a combination of any two living breathing entities. And that includes all you sci-fi lovers and others having relations with "aliens".

The problem is trying to figure out which one is the alien!!!

Parents are forever.

Hey Dad, how about that allowance you promised me?

Who says balding is hereditary from the mother anyway!

Two moms create an economic problem only on holidays otherwise they are great!
