“A guy walks into a bar…” is a typical form of what has been called the “bar joke.” A limbo dancer version of the joke is:
 
“A limbo dancer walked into a bar…and got disqualified!”
 
“A limbo champion walks into a bar, and says, ‘OW! DAMMIT! MY CAREER IS OVER!’” was cited in 2006. “Two limbo dancers walk into a bar…and lose” was cited on Twitter on June 18, 2009. The joke has been printed on ecards.
   
“A horse walks into a bar. Show jumping at its worst” is a similar joke. The horse has to get over the bar, while the limbo dancer has to get under the bar.
         
     
Wikipedia: Limbo (dance)
Limbo is a traditional popular dance contest that originated on the island of Trinidad. The dance originated as an event that took place at wakes in Trinidad and Tobago, and was popularized by dance pioneer Julia Edward (known as the First Lady of Limbo) and her company which appeared in several films, in particular Fire Down Below (1957), and toured widely in the Caribbean, Europe, North and South America, Asia and Africa in the 1960s and beyond.

Rules
A horizontal bar, known as the limbo bar, is placed atop two vertical bars. All contestants must attempt to go under the bar with their backs facing the floor. Whoever knocks the bar off or falls is eliminated from the contest. After everyone has completed their turns, the bar is lowered slightly and the contest continues. The contest ends when only one person can successfully “limbo” under the bar.
