Clutch problems!!!

I've got a 91 honda civic hb. After the car warms up and a little driving the clutch will grab all the way down at the floor, then slip out. I know the clutch is bad but i'm wondering what else could cause this.

Well, first of al the clutch is bad... You should try adjusting it from the little knob in you engine bay that is on your clutch cable... If this only hapends sometimes then you have realy nasty clutch drag and I sugest you replace it before you get stranded. :2cents:
