While trying to explain ROFL to Marie at happy hour last night, Carina helpfully explained that it was just like LOL.
Carina: It's just like LOL. Except that you're rolling on the floor.
Carina: Right, laughing.
skippy: Because otherwise it'd just be ROF.
Mike: Maybe you're on fire?
skippy: Stop, Drop, and ROF
Carina nearly spilled her beer from laughing so hard (she was LOL!).
The point of this entire conversation was an attempt to explain the ROLFcopter image:

Scott sends word of ROLFCAT, for more LOLing!
