There once was a fisher named Fisher,
Who went fishing for fish in a fissure,
A fish with a grin,
Pulled the fisherman in,
Now they're fishing the fissure for Fisher.


(I think 'photographer' is too long for limericks.)
naaawww... let's see.

A photographer, needing to share,
Was framing his subject with care,
He took a step back,
Fell down with a smack,
And the picture showed nothing but air.

hmmmm...best I could do.
