My first exposure to Vos was on Last Comic Standing where he did a lot otf off-stage antics with Dave Mordal. I always thought Mordal was the funnier of the two.

Of course since the show was rigged and Dave Mordal was an "edgy" comic, the producers had him lose in week three, or something ridiculous, to "family friendly" Dat Phan. Mordal got ripped off and was always funnier than Vos.
