Jellybean stuck

My 2.5 year old just said (and I quote, exactly): "But mom, I have to put my fingers in my mouth a-cuz I have a jellybean stuck in my teeth. OK?" (after I told him to keep his fingers out of his mouth). I'm pretty sure, although he's been saying complete sentences for many months now, this is probably one of the longest- intelligent, reasoning sentence I've heard, lol.
