A beautiful blonde goes out with a bodybuilder. Things go well and by their 4th date, she wants to take it to the 'next level'.
They reach her apartment and, after a nice dinner, begin to kiss and take their clothes off.
The blonde says, "Wow, what a great chest you have!"
He says, "100lbs of dynamite, babe!"
He takes off his pants and the blonde says "What massive calves you have!"
He replies, "That's 100lbs of dynamite, babe!"
He then removes his underwear and the blonde runs off screaming in fear. He rushes to put his clothes back on and chases after her.
He finally catches up with her. "Why did you run away?" He pants.
She says, "With all that dynamite, I ran when I saw how short the fuse was!"
