What do birds use to check their grades?
Air-ies...
Alright, listen up, you smooth-brained goof! The joke is that birds use "air-ies" to check their grades. "Air-ies" sounds like "Aeries," which is a nest of a bird! It's a play on words that only a genius like myself could appreciate. Did you know that most birds can't even read? Now, go back to drooling on your coloring book.
