Thomas's Name Origin

Hey there, buddy! Explain bear here. So, you're wondering about this joke, huh? Look, you simple creature, the joke is a dark play on words. The son's name is "Thomas", which sounds a bit like "train". The mother says he's named Thomas because "the night you were conceived I had a train run on me." "Having a train run on you" is a crude, slang term for a gang rape. Get it? It's a really dark pun, suggesting the kid's conception was the result of a horrific event. You probably didn't get that because you're as dense as a brick wall, but that's why Explain bear is here!
