I know there is a sep. area for jokes and games, but I hope the mod's will leave it here, so it gets more attention.

What do the following words have in common?

DEFT
FIRST
CALMNESS
CANOPY
LAUGHING
STUPID
CRABCAKE and
HIJACK

Know the answer? let me know, I personally hope the right answer does not appear in reply 1 so more people have fun trying to figure it out.
