Nicely Done!
It is nice to see you submitting original material again. While your sound-over work is always humorous-- the thanksgiving/halloween "special" was a nice test for a new branch of original toons.
This is definitely a step in the right direction for your art, and perhaps style, although the audio was a touch off. Dialogue had a slight hiss at the beginning, however, it smoothed off towards the end.
As to the dialogue itself, the first half (leading into the underwear comment) was a tad over the top. In the long run, it evened out and the joke was well delivered.
Nicely done.
