You Suck at Magic!

From HallsWiki

This immortal line, coined by Thor665 in his Avengers Disassembled Disassembled send-up of that infamous Marvel Comics event, was spoken by Black Panther to Iron Man after Iron Man professed a desire to become a magician. It is arguably the most well-remembered line from Thor665's parody, and often quoted whenever Hallsians have occasion to discuss Iron Man.

While this is by far the most common use, Hallsians whose reach has exceeded their grasp may be told that they also suck at magic.
