A limerick ... a dirty one

I remember when we visited Nantucket Island and Brian told Howie this entire limerick. Howie was in frickin' stitches about it, giggling for the longest time. And since I can't come up with a single G- or PG-13 rated topic to blog on, I've gotten B to say it nice and slow for me, so I can post it up here.
There once was a man from Nantucket,
whose d*ck was so long he could suck it.
As he said with a grin,
while he wiped off his chin,
"If my ear were a c**t, I could f*ck it."
