WTF?--part 3

So, yesterday we were at Safeway & I was waiting at the Starbucks kiosk, which was taking awhile as they were busy. I looked down & my son had his pants & underwear COMPLETELY PULLED DOWN. What the f--- was this? It was like the Vienna sausage aisle visits Starbuck's. I was MORTIFIED! I asked the young lady, who happened to be an employee on her break, if perhaps he had urinated on the floor, thinking that that MUST be the reason behind this exhibition, but apparently not. I tell you, that would have been one fast getaway if he had. (No, not really...I would have let them finish making my latte & THEN split!) What was he thinking?
