Here's what I liked:
-The animation was exceptionally smooth. I rarely see anything so smooth. Good work.
-The audio was really solid. Both the voicework and the music were really good.
Here's what I didn't:
-This wasn't very original. This joke's been done to death. I can even remember seeing the whole "with your help I can be rich" thing way back on In Living Color like two decades ago. This video didn't bring anything new to the joke other than screaming.
-The screaming. Humor comes in many forms. Sometimes humor comes from complete stupid nonsense (which makes me laugh), sometimes it comes from excessive amounts of violence or swearing (which makes me laugh), and sometimes it comes from clever wit (which makes me laugh). This attempt at humor comes from volume, in the vein of Chris Farley for example. Some people, apparently including yourself, believe that the louder someone gets the funnier they become. That doesn't do it for me though.
-The art was inconsistent. While the animation was great, when the talking guy started to scream the art style drastically changed. Ren and Stimpy did this well, but all of the imitators (such as this flash) just end up looking rather ugly.
Overall, this wasn't a bad flash, though it wasn't groundbreaking either. Above average.
