Danny McBride told Jimmy Kimmel on Tuesday night about his love for 'Truly Tasteless Jokes', a series of books released in the 1980s full of crude jokes.
However, McBride says he didn't expect his five-year-old son to repeat on of these 'Truly Tasteless Jokes' to his entire preschool class.
The actor says he purchased one of the joke books on eBay, and reads aloud from it to annoy his wife, but he was certain his son wasn't listening.
The 'Eastbound and Down' star says it wasn't long, though, before his wife got a call from their son's school saying he had gotten up in front of his class to say, "What's the difference between a wife and a girlfriend? About 60 pounds."
McBride says he explained to him why that wasn't appropriate, and also how it's really more like 40 pounds.
