Shit, is this still going?

When Roger got married for the fourth time, he asked me to be his best
man. He said it was because I was the only person that he didn't owe
money to. Even so I was very honoured that he'd chosen me. I was also
very nervous. Especially about the idea of giving a speech. I've never liked
standing up and talking in front of people.
"Don't worry about that you big warty fanny," Roger said, "just start off with a
good joke. It'll loosen everyone up and then nobody will mind any of the
other tedious drivel you'll have to say."
I took his advice and looked on the internet for all the jokes I could find. It
took a long time, but eventually I found one which I thought would make
people laugh.
When my big moment came, I stood up and tapped a spoon on my
wineglass to get everyone's attention. When they had all stopped talking
and were looking at me expectantly, I said: "Ladies and Gentlemen, there
was this man who was sent to prison for the first time. He was very nervous
because of all the stories he'd heard and found himself sharing a cell with
a huge, shaven-headed man with a tattoo that said: "I shag arses". Just
after lights out, his worst fears were realised when the bald man said 'Right,
do you want to be Mummy or Daddy?' 'Daddy,' the man replied. 'Good,' the bald man said, 'now get over here and suck my cock, Daddy!'"
Only a couple of people laughed. Roger glared at me and the bride glared
at Roger.
One of the bridesmaids started crying.
And then somebody asked me quietly to leave.
