Yungerer is a corruption of Uri Geller (with リ ri replaced by the
visually similar ン n), who claims to have the ability to bend spoons
with his mind, as the Japanese names of the Abra line are based on
famous mystics. Geller attempted to make a case against Nintendo of
America for using his likeness in a character and lost, Nintendo's
defense being that they had not named any Pokémon after actual people.

Basically some "Magician" thought he could bend spoons, so he sued Nintendo for using him. He lost xD
