I found a problem with Stinky!

Ok, so it's not serious. Do you remember catching leaves on fire with magnifying glasses as a kid?

I sat down today to smoke a cigar. I set out the ashtray and went inside to grab some stuff. Well, I happened to put it in the perfect spot to reflect the light in a single beam back into the bowl. The beam focused on an old cigar nub. I came back outside and smelled smoke. I thought it was strange, but couldn't find a source. The next thing I know there is smoke pouring out of the Stinky. Apparently, it caught fire faster than John's beard. I quickly moved the bowl out of the sun and swirled the bowl just a little to move the smoldering cigar into some ashes. It was pretty funny. The only fix I can think of is to make sure the bowl stays more full in the future.

Has anyone else had this happen?
