The "Lazy Chef" sketches typically don't have any outside influence when they're written. This particular episode is actually based off a demonstration a classmate gave in a speech class (although he did have the materials with him). This was our final speech for the class and was supposed to last 10-12 minutes. Needless to say, he didn't do well. I think he thought offering the teacher an ice cream float was bribery enough to get a passing grade.
