Sans the skeleton

A very powerful character in UnderTale, he likes to make puns that his brother The Great Papyrus hates. Sans also appeared in Deltarune.
Quote from Deltarune:"too late. I already befriended your mom last night.

Guy 1: this box weighs a ton!
Guy 2: A skele-ton?
Guy 3: Please no, please don't make puns like Sans the skeleton...
