[Daffodil]

Callum himself is proud of his imagined likeness to Jim Carrey and there is a vid somewhere of him doing a Carrey gurn.
Unfortunately Callum gurns the whole time anyway. His mouth is very lizard like and when he talks to anyone he waggles his head and looks away a lot, which is why he seems very insincere. The longest time he looked directly at someone was when he was staring at Dexter in the shower.
