Delia spent the weekend at my brother's last week, and recently my sister-in-law remembered to tell me a little story about a trip to Costco that they made while she was there.
It seems that my brother separated from them and was elsewhere in the store and Lisa (his wife, my SIL) asked Delia, "I wonder where your Uncle Craig went?" and Delia said in response, "Where's Uncle Craig and his imaginary buttcheeks?"
I am still laughing. My brother is such a sport.
Albeit one with no ass to speak of.
