Dad's Humor... a blessing and a curse

Last night, before bed, I was looking at our white towels hanging in the bathroom.  

Brian's was looking especially dingy.  I went to bed and told him I thought it was time we switch out our towels.  He said, "Okay, yeah."  I said, "Yours is looking like the olympics."  He said, "What?"(said in a higher pitch and drawn out.)   I said, "It's Beiging!  Ha ha ha ha ha!"  He shook his head and said, "How long did it take you to come up with that one?"  I said proudly, "That's just how my mind works."  

Thanks Dad!  :)
