Blue Balls

Let me set this up for you....

Yesterday, it was busy because of the Christmas season and I was cashiering. A lady walks up with a bunch of racquet ball items and she has her like 4 year old daughter with me. She puts her items up on the counter and I notice she wants to buy a large container of racquet balls, which obviously means all the balls are blue. So, here's how it goes...

Blair: That's a lot of blue balls!!!....uh....uh

Customer: Yes it is!

I am not quite sure if she caught what i was saying but I couldn't stop laughing because I am that immature.
