“A Roman walks into a bar, holds up two fingers…” (bar joke)

“A guy walks into a bar…” is a typical form of what has been called the “bar joke.” A Roman numeral joke is:
 
“A Roman walks into a bar, holds up two fingers, and says, ‘Five beers, please!’”
 
The two fingers form the V sign—the Roman numeral for “five.” “An ancient Roman walks into a bar and orders five beers” was cited in 2011. “A Roman walks into a bar, holds up two fingers, and says, ‘Five beers, please’” was cited on Twitter on June 25, 2013.
 
“A Roman walks into a bar and orders a Martinus…” is another bar joke involving a Roman.

This historical side-splitter relies on a knowledge of Roman ­numerals. The Roman will be able to order his round using just two fingers because five is V. Make sure the landlord is a pal with a sense of ­humour before trying this in your local.
