“A snail walks into a bar…” (bar joke)

“A guy walks into a bar…” is a typical form of what has been called the “bar joke.” A snail version has been cited in print since at least 1997:
 
“A snail walks into a bar and orders a beer. The bartender takes one look at it and says, “Get out! We don’t serve snails here!” He picks up the snail and throws it down the street. One year later, the snail shows up on the bar and says, ‘What did you do that for?’”
 
The snail joke without the bar has been cited in print since at least 1992 and 1994.

Heard this on the radio this morning (I’ve modified it tho)
 
Two politicians were walking through parliament, when one of them turned around and squashed a snail under the heel of his shoe.
 
His mate asked “What did you do that for?”
 
To which he replied “That bastard’s been following me all day!”

A man was sitting at home watching TV and his doorbell rang.  When he answered it there was nobody there, just a snail on the step.  He kicked the snail and it ended up half way down the street.  A year later the same man was sitting at home, watching TV and his doorbell rang. He opened the door and again nobody was there, just the snail.  It looked at him and said, “What did you do that for?”

It’s Christmas time and a family are just sitting down to have their christmas dinner when there’s a knock at the door. The father gets up and answers it, but theres nobody there. He’s about to shut the door when he hears a tiny voice.
“oi”.
He looks down and, on his door step, theres a snail.
Man - “What do you want”
Snail - “Can I have Christmas dinner with you and your family?”
Man - “No”
And he picks up the snail an throws it in the garden.
Anyway, the next year, the family are sitting down for Christmas dinner again when there’s a knock at the door. The father gets up and answers it, but theres nobody there. He’s about to shut the door when he hears a tiny voice.
“oi”.
He looks down and, on his door step, theres a snail.
“What did you do that for?”

A Snail Walks Into a Bar

One Christmas Eve, a barman looks down and sees a snail on the bar. “A pint of bitter, please,” says the snail.
 
“I’m sorry,” the barman says, “we don’t serve molluscs.”
 
“Why not?” asks the snail.
 
“We just don’t. Piss off.” And with that the barman flicks the snail off the bar.
 
The next Christmas Eve the barman looks down and sees the same snail on the bar.
 
“What did you do that for?” asks the snail.

Quick bartender joke:
 
A snail walks into a bar and orders a beer.  The bartender takes one look at it and says, “Get out!  We don’t serve snails here!”  He picks up the snail and throws it against the wall.
     
Six months later the snail shows up on the bar and says, “Was that really necessary?”

A snail walks into a bar and asks the bartender for a drink. But the bartender says “We don’t serve your kind here!” So the bartender kicks out the snail. A few weeks later the same snail walks into the bar and says to the bartender “Why did you throw me out?!”

I’ve heard it as…
 
A snail rings a man’s doorbell. The man opens the door, sees the snail, picks him up, and tosses him across the driveway. A few weeks later the man’s doorbell rings again. It’s the snail and he says, “What the fuck did you do that for?!?!”
