He got dressed in only his swimsuit, made a sign that said “Will you go to prom with me? I won’t get dressed unless you say yes”.

He held the sign in a way that it covered his body from just above the knee to his chest, so it looked like he was completely naked. He stood on the porch and had his buddies ring the doorbell. Of course, the girl’s mom answered the door. I heard the mother was mortified and mildly amused and the girl turned bright red and covered her face.
