On Three

Go To

Chandler: Okay, on three. One... Two...
Joey: Why don't we just go on two?
Chandler: Why two?
Joey: Because it's faster.
Chandler: Yeah, I coulda counted to three like four times without all this "two" talk.
Friends, when the gang is lifting a heavy entertainment center into place

Any time precise timing is called for, you're likely to hear the phrase "On three: One, two, THREE!"

Since this has been heard countless times before, variations are common. A common parody is: "WAIT! Do we go on three, or do we say 'One, two, three' and then go?" This usually results in an awkward conversation about how best to count or the characters becoming even more confused and going at the wrong time or missing their opportunity entirely. (Genre Savvy characters may avoid this by counting down from three instead: "Three, two, one, GO!") Another common joke is to have someone simply go "Three" without counting to one or two first.

If the action which the count builds up to is a painful one (e.g. ripping duct tape off a bound captive's mouth), then the action may be taken before reaching the promised "three", to get it over and done with before the subject of said action realizes it's started.


The reason why "three" is the usual number is because it's the smallest number of points you can use to establish a regular time interval. If you only count to one, nobody can react fast enough to the person saying "one". If you only count to two, you don't know how long the time is supposed to be between numbers, so nobody knows when to listen for the "two" either. Counting to three establishes both the point in time and interval between numbers, so everyone can figure out when the "three" will happen.

Sub-Trope of Rule of Three. Not to be confused with Counting to Three, which is when you don't want the person counting to get to three, or with One, Two, Three, Four, Go! (in which the "go" is the Japanese word for "five").

Not to be confused with the film On The Count Of Three, although this trope is mentioned and parodied in there.
