Limerick challenge

[hepkittn]

I made a comment on a friend's Facebook page, and parenthetically mentioned that my comment sounded like the first line of a limerick. Another friend of this friend made comment that he was unable to come up with a suitable limerick... Naturally, I saw this as a challenge.

The first line was "I once knew a guy who used Nair"...

I once knew a guy who used Nair
Who was given to dramatic flair
"T'will improve the aesthetic,
The size seem less pathetic..."
Yet it seems all he had was the hair.
