"Doctor, I have a problem..." "What’s your problem?" "I pee in my sleep, every night!" "Why?" "Oh, well... Every night, a little devil visits me in my sleep and asks me; “Did we pee today?”. "And, that’s it? The solution is so simple.. Listen to me! If the little devil comes again you’re gonna answer; 'Yeah, dude, I did!'" "And that will cut it off?" "Sure! Like a knife!" At night, the little devil showed up on the patient’s dream and whispered; "Did we pee today?" "Yeah, dude, I did!" said angry the guy. And little devil replied: "What about poop?"
