There is a T that Haunts Me

I saw it.
I finally saw it.
I finally saw it one day.

I forget.

I forget what I saw.
I just had it.
Do you have it?
Please give it.

Don't pawn it.
Don't push it.
Just drop it!
(I dropped it)
And (But) I don't mind.

There is no fine
for being a bull.
(You thought I said swine).
