Inspired by this thread, the challenge is to come up with an original “A (blank) walks into a bar…” joke. It has to be totally original-I and other posters will be checking the internet. If we happen to get more than one original, there will be a poll to pick the best one.
BTW, personally I don’t think it’s possible. 
A Doper walks into a bar. Bartender says, “I guess you want it straight”.
A man walks into a bar. Bartender says, “What’ll you have?” Man says, “I’ll take a Sharknado.” Bartender says, “A Sharknado? What’s that?” Man says, “Oh, it’s great. It’s got bite. But, it does give you wind.”
The Building Code Inspector in San Francisco walks into a bar and tells the bartender that the front door is in violation as it opens inwards.
The bartender replied, “It’s OK, the door swings both ways”.
A man walks into a bar. The bartender says “Cite?”.

A man walks into a bar. He says “Give me 1 Rob Roy, 2 Bud Lites, and Hi Opal!”
Thank you for prompting me to create a new rule:
It has to be considered funny by the general public.
Telling a joke that would only be understood by Dopers, or told in a foreign language, or told in binary would certainly be original, but it’s not what I’m looking for.
Edward Snowden and a referee walk into a sports bar that caters to referees. The bartender says, “Get out of here, we don’t serve whistle blowers.”

Search parties have been sent.
A man walks into a bar that has an “American Pioneer” theme-rough hewn handcarved tables and chairs, pewter beer mugs, and pictures of famous mountaineers and adventurers like Mike Fink, Daniel Boone, Jim Bridger and Kit Carson…but the man notices that one picture in particular seemed to be missing. He asks the saloon keep, “Why are there no pictures of Davy Crockett?”, and the keep replies “Ain’t no saloon will have anything to do with Crockett because of what he did.” “What did he do that pissed you guys off?”
“He shot up a b’ar when he was only three!”
A man walks into a bar and says, “Ow!”
Definitely not original.
LOL, I love yours Czarcasm!

Not really-different joke using same Crocket line.

Apologies to all. Warning: limerick
A man walks into a bar
But is banned because of his scar.
The last time was so drunk,
He made out with a skunk,
And his nose fell into the tip jar.
EWWWW! Apology not accepted. You owe me a shot of applejack and a picked egg.
