There once was a man who had ripped pants He kept his legs close whenever he danced

He never got new ones cause he had to pay
I don't have no money is what he would say

i got that so far i know i need one more line but i don't understand what i should say would it make sense to say the man never got have new pants

Just because it has five lines and rhymes, that does not make it a limerick. There is a certain very strict meter which must be followed. Read a bunch of them, then try again. Your meter is way off.

The rhythm must be as in

There was an old man from Nantucket
Who kept all his cash in a bucket.
His daughter, named Nan,
Ran away with a man,
And as for the bucket, Nan tuck it!

The best limericks, besides having good scansion and rhyme, usually contain an amusing twist in the last line, as in

A limerick's never averse
To expressing itself in a terse
Economical style,
And yet all the while,
A limerick's always</it> a verse!

oops - bad closing tag...

Yes, it would make sense to say that the man never got new pants. It would complete the rhyme and further emphasize the situation of the man not being able to afford new pants. So your next line could be:

"The man never got new pants, in his ripped pair he'd always prance."
