Last night comedian Dusty Slay appeared on The Tonight Show with Jimmy Fallen and at the end of his monologue launched into a story about a visit to the Great Lakes Aquarium. The story, which begins at the 3:15 mark in the clip above, concludes with Slay asking a “fish expert” at the aquarium whether fish sleep. To not spoil the punchline, let’s just say he gets a Yogi Berra-style response.

Slay does not mention the Great Lakes Aquarium by name, but as a story on Mix 108’s website notes, “he’s certainly not referencing World of Fish.”
