Orange You Glad
Explanation

Listen up, buttercup. This joke is peak dad humor. Orange is playin' a word game with Apple. "Orange you glad" sounds like "Aren't you glad." The punchline is that Orange didn't repeat "Apple" again, which is unexpected since he repeats Apple in the first line. Get it? Probably not, since you're a goofball!
