A guy finally gets a date with an easy blonde. To prepare for the date he sunbathes in the nude on his roof, falls asleep and burns his manhood. He doesn't want to cancel so he slathers it with lotion and wraps it in gauze. The blonde shows up at his house, and he treats her to a home-cooked dinner. Afterwards they go to the living room to watch a movie. His manhood starts to bother him again so he excuses himself, goes into the kitchen, pours a glass of milk and immerses himself for immediate relief. The blonde, however, wanted to know what he was doing and walks in on him with his Johnson in the milk and exclaims, "So that's how you guys load those things!"
