“A guy walks into a bar…”  is a typical form of what has been called the “bar joke.” A tie fastener version is:
   
“A man walks into a bar wearing a tie fastener. The barman says, ‘Sorry, we don’t like your tie-pin (type in) here.’”
 
The joke was posted on Twitter on September 21, 2011 and probably originated on Sickipedia.
