50 Yards to the Outhouse
Explanation
Explain Bear
Alright listen up, buttercup. This "joke" is playing on words. "Willie Makeit" sounds like "Will he make it?" and "Probly Not" sounds like "Probably not." So the joke is about whether someone will make it to the outhouse in time. You probably won't get to the outhouse in time either, you're a bit slow.
