any skits about the "moderate to severe" testimonials in ads?

I see a lot of drug commercials where a person talks about their “moderate to severe” whatever. Sounds like great joke fodder to me.

Has anybody come across a comedy skit (on SNL, Mad TV, youtube, etc) based on this idea?

On a related note, does anybody know how to submit comedy ideas to the writers for those things?

You would most certainly need an agent. I doubt they take any material from outside the “writing staff”.

Not a skit, but MAD Magazine did this in print at least once.

The Happy Fun Ball commercial makes fun of disclaimers like that. Sorry for the weird link, SNL tends to keep things off of YouTube.
