[Calvin Locke]

Alton Brown used a big flower pot as a smoker in an "Good Eats" epi.

(He also used a big cardboard box...for fish..., but that's probably not what you're looking for...)

I think I recall seeing Alton with his big flower pots. I think he also did something with smoking bacon - ‘Scrap Iron Chef’ (?)
