“Two men walk into a bar. The first orders H2O…” (bar joke)

“A guy walks into a bar...” is a typical form of what has been called the “bar joke.” A popular science joke that has been printed on many images is:

Two men walk into a bar.
One man orders H2O.
The other says, “I’ll have H2O too.”
The second man dies.


The second man was given hydrogen peroxide (H2O2). The joke has been cited in print since at least 2005, when it was posted on Slashdot.

Another version of the joke (with an altered punchline) has been cited in print since at least 2012:

Two chemists walk into a bar.
The first one says, “I’ll have some H2O.”
The second says, “I’ll have some water too. But why’d you order it like that? We aren’t at work.”
The first chemist excuses himself and weeps in the bathroom.
His assassination plot had failed.

Two chemistry majors walk into a bar. The bartender says to the first, “What can I get for you?”
“H2O.”
“And you,” asks the bartender?
“I’ll have an H20, too.”
The second guy died.

h2o2
H2O2 is the chemical formula for hydrogen peroxide (the stuff that comes in a brown bottle that stings when you put it on cuts)
Two chemists walk into a bar, one says, “I’ll have H2o” the bar tender hands him a glass of water. The next one says, “I’ll have H2O, too” he gets handed a drink as well ... He dies ...
H2O2 is a chemical formula.
