These are of Seth sneaking back for a follow up cupcake after everyone had polished off their first round. And for the record, I imagine him speaking these comments with a very cultured British accent.
"I could have sworn I just had a birthday, but there appear to be three candles on this cupcake! Telling time is difficult! Oh well...I guess I turned three early!"
"You're right, sampling icing from a candle is much classier than using my fingers. I got a little ahead of myself before. I do prefer to stay clean at all times, as you can see from my spotless face and apparel."
