Can you have multiple-word homophones? If not, what would such pairs of same-sounding multiple words be called?
There is the funny/children's rhyming poem Fuzzy Wuzzy:
Fuzzy Wuzzy was a bear.
Fuzzy Wuzzy had no hair.
Fuzzy Wuzzy wasn't fuzzy, was he?
The punchline of the joke in this poem is in the last line where the bolded sections are unexpectedly pronounced identically. (At least, I know American & British speakers who 'get' that joke).
Going on this definition of homophone:
a word pronounced the same as another but differing in meaning, whether spelled the same way or not
the sounds made up of multiple words seem to fall outside of this meaning. Also "Wuzzy" seems to not be a "real" word (with a definition) or at least is only used in this context. Other definitions I've read seem essentially the same.
So, are "wuzzy" and "was he" homophones? If not, what are they (if anything)?
I wasn't able to find attribution for this poem but would add it if anyone knows it. Wikipedia at least has little detail.
