Crank arms stuck

Does anyone have any suggestions for getting crank arms off when they are stuck and the crank puller/extractor doesn't do jack?

What do you mean the crank puller doesn't do jack? If they have been on there for a long time you might try spraying a bunch of penetrating oil in the area (liquid wrench or WD-40) and letting it sit a while.

What interface is it? Isis? Square Taper?

Depending on the puller you have, it should rip out the threads on the crank before it stops turning granted it's hardened steel with fine threads (park version)
