Yo, I gave my roomate a sleeping dragon last night. It was hilarious.

A single, long turd that is just barely visible in the bottom of the toliet. The turd is left for discovery by the next user of the device. Like a dragon in its cave...
I discovered a big sleeping dragon in the toliet this morning after my roomate left.

Yeah, laugh all you want now ladies, come to my place and I'll show you it's a sleeping dragon.
