No, No, No! You're all wrong. A Lincoln Log is when you drop a loaf that's so big and solid that it by itself (without any t.p.) can plug the toilet. if the toilet doesnt plug then it's not a Lincoln Log. Officially it has to be one of those high pressure flushing public bathroom toilets for it to be a real Lincoln Log. You know, those toilets that flush with the sound of a jet taking off. Ever since my good friend Big Head Ed introduced eating regular fiber in his diet nobody has been able to create real Lincoln Logs, so out of traditional honour the standard has dropped to any type of toilet. And please people, lets capitalize the words Lincoln Log. Show some respect for its glory!
Mike: "AH! Yuck, somebody passed a smelly ol' Lincoln Log in this public washroom!"
Albert: "I kind of like that smell"
Other person in the washroom: "That's gross!"
