What Fruit Has Seeds On The Outside?

When taking the Bronson exit off the 417 to get to the airport, which is what we were doing one day as Mike drove some other Dudes to their flight, you pass an old dry cleaners, the kind of business/building that would have been normal years ago but now sticks out as a relic. The building has an old-style marquee/message board wrapping around the entire building, where letters can be manually inserted one by one to create a message. The proprietors used to create friendly little messages on the board for the people driving by.

On this day, we pulled up to the intersection next to the dry cleaners, and there was a message on the marquee that we all read. The message read exactly this: It was an interesting little trivia question, offered to those driving by... and it gave you no opportunity whatsoever to think about it or make a guess. It just frames it as a question, then instantly answers its own question. There's not even any punctuation to warn you, perhaps because they didn't have any to add. It felt like there was at least an opportunity to, like, put the answer on the line below or something. Nope.
 * WHAT FRUIT HAS SEEDS ON THE OUTSIDE ANSWER STRAWBERRY

It was slightly absurd, and so of course we loved it. Moving forward, it became popular to bark out the entire quote very quickly, or when someone asked a question to immediately respond "ANSWERSTRAWBERRY".
