Hot dog

Riddle
A girl goes into a room with a single hot dog 30 seconds later it's gone. She didn't eat it and there's no furniture in the room, so where did it go?

Answer
IF GRILLING IS SURE TO RESULT IN HOT DOGS, THEN YOU MUST GRILL!

...

Sun Tzu said that. And I'd say he knows a little more about grilling, pal, BECAUSE HE INVENTED IT. And then he perfected it so that no living man could best in him in the backyard of honor!
