You get a lot of bacteria growing on the tongue usually but also in the pharynx, and those bacteria produce compounds called volatile sulfur compounds.

What I'd recommend is that they brush their teeth extremely well but also brush their tongue and use one of the tongue scrapers.

Many of the drugs that are given, usually for older people, actually cause dry mouth so that those people have to be more careful with their brushing and cleaning.

I think the problems with comedians that are political, and there are some brilliant ones, are the ones that offer no solutions. Not that there's a moral obligation for a comic to fix things, but I like to see a comic that's upset about something and offer a solution. It can be a funny solution. I like to see the thought process.

In 2007, I had on-paper success. I got to go to that Aspen comedy festival, which was pretty exclusive, I guess. Then I did Carson Daly. That was enough validation.

I don't want to make it a hard, fast rule, but it's surprising how many 'fun for the whole family' acts are real scumbags. The people that confess they're scumbags on stage are generally really great people. They're more honest with the audience with who they are.
