Not very creative. . .
This flash was pretty decent, but it didn't keep me interested. The animation was very basic, and unintriguing. I often find myself watching a great flash and wondering "Oh wow! How did they do animate that?!", but this didn't do it for me. The art somewhat inhuman, and boring looking. The background was also a little disappointing. Your lip-syncing was okay, but there's definitely room for improvement. Your "frame-by-frame" animation was pretty weak as well, but all around it wasn't that bad.
In terms of audio, this had an alright feel. Clearly, there's not much to be said here, considering it's a clip from an audio routine. The audio quality on the clip wasn't perfect, but there's only so much you can do sometimes. Maybe you could have amplified the audio and put some chill jazz behind it to keep the viewer interested, but the way you did it was okay.
Normally, I'd comment on the writing, but there wasn't any, since it was someone else's. It was a funny clip, and I like Bill Hicks, so good pick.
All things taken into consideration, I'll conclude by saying you did an alright job on this flash. Could've been better, could've been far worse. I'm going to vote four, because I liked the submission, and I don't want to lower the score.
