Making a Sandwich

A woman and her little boy were walking through a park in New York and they pass two squirrels having intercourse. The little boy asks his mom, "Momma, momma, what are they doing?" The lady responded, "They're making a sandwich."

Then they pass two dogs having intercourse and the little boy again asks what they were doing. His mother again replied they were making a sandwich.

A couple of days later the little boy walks in on his mother and father and said " Mommy, Daddy, y'all must be making a sandwich because, Momma has Mayonnaise all over her mouth!!!"
