I actually enjoyed this enough to review.
The animation was a bit sketchy in segments, but with the cartoony art style and feel of the whole flash that's completely forgiveable.
I especially enjoyed the little cameos you slipped in, such as Samuel L. Jackson and Tobias from Arrested Development. You did really good work on likenesses, which can be difficult. Total kudos for that.. Though I must ask, did you actually draw Bill & Ted or did you just use an image from their 90's cartoon?
The audio itself is quite funny and well-made, I'm surely using that download link to add it to my own playlist. At first I almost thought it was They Might Be Giants or another well-known, signed act of the sort.
The only downside I saw to this whole flash was the ending. Somehow the seppuku down ending just reduced the funny. Other than that, this was a great flash, and I look forward to seeing more work from you. :)
