# “A mathematician walks into a bar and orders ten times the drinks of everyone else…” (bar joke)

“A guy walks into a bar…” is a typical form of what has been called the “bar joke.” A mathematician version is:

*“A mathematician walks into a bar and asks for ten times the normal number of drinks anyone else has. ‘Wow,’ says the barkeep, ‘That’s an order of magnitude!’”*

The joke has been cited in print since at least 2009.

“An infinite number of mathematicians walk into a bar…” is another mathematician bar joke.

Wikipedia: Order of magnitude*Orders of magnitude* are written in powers of 10. For example, the order of magnitude of 1500 is 3, since 1500 may be written as 1.5 × 103.

Differences in order of magnitude can be measured on the logarithmic scale in “decades” (i.e., factors of ten).

If math is more your thing, there’s this classic set-up:

*A man walks into a bar and asks for 10 times more drinks than anyone else. The barman says, “Now THAT is an order of magnitude!”*
