I used to love those! One of my favorites as a kid - they had the best cereal back in the early and mid 80's. Ghostbusters, Croonchy Stars, C3PO's, Nerds Cereal, those were the days. Mom wouldn't let me have em for breakfast though, only for my snack and when I was at Grammas (she let me have em in the morning).
The dream bit would be for Howard to come out to Jerry's car in one of his signature douchebag costumes, Jerry does one of his "Seinfeld" takes and says "No..I'm sorry...You'll have to change...I just can't be seen with someone dressed like that".
