Smoking Chain Lube

I dropped by REI this afternoo to pick up some lubrication for my bike. The back derailer was annoying me this morning. While reading the back of the cans I noticed an interesting warning on one of them.

DO NOT SMOKE

The first thought I came up with was "How on earth do you smoke chain lube"? This was soon followed by several other along the lines of "why would you ever ...".

It occurred to be about 5 minutes later that they really intended for it to mean "Do not smoke ... around the chain lube." Seems like the better warning would be the more complete one. For what if some wonder started pondering the question of how to smoke chain lube and lit up a cigarette for thought?
