->'''[=SpongeBob=]:''' But, Patrick, we promised!\\
'''Patrick:''' Well, I had my fingers crossed!\\
'''[=SpongeBob=]:''' You don't ''have'' any fingers, Patrick.
-->-- ''WesternAnimation/SpongeBobSquarePants'', "[[Recap/SpongeBobSquarePantsS1E20HookyMermaidManAndBarnacleBoyII Hooky]]"

Sometimes when a character is forced to make a vow, oath, promise, gesture, etc. they don't actually mean, they will cross their index and middle fingers in a way hidden to the character they're talking to but visible to the audience, to show they're actually lying. Most often the person will have their crossed fingers held behind their back, but off to the side, under a table, or somewhere else hidden is also possible.

TruthInTelevision, of course, which is the reason why it works as a visual cue, often in the form of AnInsert. There's a number of guesses out there as to why it became a common gesture for lying, but the general idea is that it somehow either protects you from the [[BoltOfDivineRetribution consequences]] of lying or absolves you from being held to your word to begin with. In real life, this gesture is mainly used by children, especially since it's not a reasonable thing for an adult to do -- someone willing to break perceived rules of propriety and conduct would generally just lie, especially since crossing your fingers risks telegraphing your falsehood to those you're trying to deceive. Therefore, the trope is generally associated with characters who are very young or just act like they are -- or failing that, very superstitious characters.

It can also be used as an OutOfCharacterAlert, both in-universe and RealLife, to signal to other people that a statement or gesture was made under coercion or otherwise insincerely. A simple example as such would be military prisoners of war being forced to participate in videos/photos either making it look like their captors was caring for them, or that the prisoners were renouncing their political beliefs. A discreet crossed finger or leg on film would be an indicator back home that the message was falsified in some way.

Not to be confused with visually similar "fingers crossed" used as GoodLuckGesture.
