You know this would be a great programming problem for CS students. Given the phrase "head less horse man", generate all 4-word phrases, repeated words allowed. (Some of the ones in this picture aren't 4 words, but anyways...)
Consider the words "head less horse man" to be digits in a base-4 number system; head=0 less=1 horse=2 man=3. Counting from 0 to (4^4)-1 would yield 256 unique values,
Bonus points for funniest picture to go with a value (must be hand-drawn by student, no AI allowed) :)
EDIT: not permutations, which I originally said. It's more of an exercise in understanding how to count in bases other than 10.
