Alice makes fun of Bob's age by suggesting that he was alive during a time period that's well beyond living memory. For example:
This could also work with Alice being a very naive character who doesn't realize how insulting she's being. Alternatively, it could involve Bob making a self-deprecating joke of this nature when he's made to feel old:
- Alice: You didn't have iPhones when you were a kid?!Bob: No, there was only so much we could pack on the Mayflower.
If the usage of this trope is followed by the revelation that Bob is Really 700 Years Old and was actually living back then, it's a Subverted Trope. If it was previously established that Bob is Really 700 Years Old, this trope does not apply at all. It is also not just any joke about Bob being old but has to include some reference to him being alive during a period in which no living person could have lived.
