In the late 1980s, while watching a friend try stand-up, David was infected by the comedy bug. Granted there were worse infections going around back then, but before he actually tried comedy himself, he spent some time as an unwitting carrier. In hindsight, the signs were obvious, as so many people close to him suddenly began telling jokes at inappropriate times - family members, co-workers, his cousin who was a nurse at a palliative care center.

Eventually, he too developed the condition, which led to multiple appearances at Just For Laughs, performances on several comedy specials, and an irresistible compunction to befriend people with cars in case he needed a ride to a gig.
