Jellybean Omelettes Can't Exist!
I was making a friend watch the episode and she astutely pointed out that if he was going to spell out "Jello", assuming he correctly got "J-E-L-L", then the next letter to come would be "O". He'd have to wait even longer without blinking to get to "Y".
Not that it really matters (I mean, c'mon, the whole show is funny because it's unrealistic and crazy), but I was like "Aww, you're right".
