Doll or blow-up doll?

My brother #1 and I were going to the grocery store to buy stuff for dinner. As I get out of the car, I noticed something odd in the backseat.

Me: Hey, what's a doll doing in the backseat of your car?

Brother #1: Oh, one of my female friends gave it to me when we went to Dave and Busters the other day.

Me: Hmm...

Brother #1: When she gave the doll, she said to me, "You need a girlfriend anyway."

I was cracking up at this point.

Brother #1: And I responded to her with a tinge of sarcasm, "Forget the doll. You might as well give me a blow-up doll."

I broke out in laughter now. Hilarious.
