Hide by the bathroom

You walk over to the bathroom and crouch down behind a machine, you can see Ron and your mother perfectly from your spot. The weight room is empty except for the three of you. You watch eagerly.

"Hey Mrs. Smith," Ron says as he walks up, "Jim said you could use a spot."

"Hi, Ron right?"

"Yeah," Ron replies as he checks out your mom.

"Please call me Kathy, you're out of high school now, and you're a grown man."

They continue with small talk for a little while, when your mom asks, "I remember you had a strange nickname, its was something pod, right?"

Ron still smiling, " Yeah, it was tripod."

"How did you get that name?"

"Well if you really want to know, my manhood is like a third leg, " Ron said proudly.

"Really?" Your mom looked at his groin.

You saw a sparkle in Ron's eyes, this was going to be interesting to say the least.
