The PS Truck

Nathan is really interested in trucks (and other vehicles) right now, so we always pay attention when a UPS truck drives by, and I point out that it's a "UPS truck."  So we were leaving Trader Joe's the other day and there was a UPS truck nearby...and I hear Nathan say, "There's a penis truck."  I sort of paused and said, "What, honey?"  And he said it again, "A big penis truck."  Yes, a "PS" truck...penis truck.  Lovely.  :)
