I always do some for form of direct forearm work, my forearms are naturally scrawny as hell so I have to do some. Besides, I love the burn I get from forearms excersises, find it more intense than any other. Usually work them say day as my bis, I'll do hammer curls, wirst curls and reverse wrist curls. Reverse wrist curls rock because they are just so damn painful for me, they'll sear so bad for me that I'll be close to screaming, hehe it's great.
