I need to remember the "sorry for the 'off-by-one' error" when I flip the bird in the future.

The joke is a reference to the index finger cursor. It doesn't really work unless you're using the middle finger in place of a index-finger-pointing-up gesture.

> index-finger-pointing-up gesture

This exact gesture is used by umpires in Cricket to signal a batsman out.

In that example the umpire's palm is facing the batsman, so that joke still doesn't work

My kids used to tell me that it was the sign for a binary 4.

Waddya mean, your kids? I learned that as a teenager myself in the 1930s, after an article in Scientific American.

"And a binary four to you"; thanks, I've just learnt a new insult - at age late 40s. :)
