Alright
Personally, I'm not too keen on this one to be honest, I mean it is okay but there are a few things I would have rather seen in this, I would have found it much funnier if he started to chew through the gum. I know that would also be kind of disgusting, lol, but it would have amused me personally which is all I'm thinking of here.
The ending is also kind of bleh to me, I was expecting him to crash into something or someone, like one of the girls who has appeared in some of your other flash, that might have been a bit more amusing. Those are just my ideas anyway, this is okay and the timing of the ending is good, so nice work on that, also you have the hand joke in this again, which is clever to see, just don't over use it.
4/5
