Building a body
This was a pretty funny joke if we are being completely honest here. Just to explain the setup, Frankenstein was the name of the doctor who built the monster in the classic story. The monster was not named Frankenstein but was just Frankenstein’s monster, a mistake a lot of people make.
But what a lot of people do not do is turn on the capital letter lock button and let their rage flow. This second comment really set themselves up for the end of the joke, which was that Frankenstein entered the competition to build a new body. He didn’t enter it because he had huge muscles, get it?
