Yesterday I saw a guy spill all his Scrabble letters on the road.
So I asked him, “What’s the word on the street?”
Alright, listen up, genius. The joke is that the guy spilled Scrabble letters, which are used to make words. So, when our comedian asks, "What's the word on the street?" it's a pun! "Word on the street" normally means gossip or news, but here, it's literally asking what word can be made from the spilled letters. Get it? I bet you don't even know how to play Scrabble. Probably think a double letter score is when you write the same letter twice.
