Picked up a sweet little generator, it just purrs.

That's nothing. Here's the one I keep in the station wagon.

 

I've got a garbage disposal that purrs:

 

Please don't mess with any fine machinery, you obviously do not understand purr.

 

Don't confuse the equipment with what you have purring in your sock drawer...

 

Whenever mine purrs in the sock drawer, it means the batteries will be all worn down and I'll have to replace them before I can use it again...
