That's only possible of course if the driveshaft is sticking out by itself.
It's more likely that the whole of the bottom end is still attached and the drive shaft isn't accessable.
In that case the only thing I've found to work is to get the engine nice and hot, then get a dustbin around the bottom with plenty of really cold water as quick as possible and as deep as possible to get the drive shaft cold as it goes up through the exhaust. The differance in temperature and expansion may free it off. Well it worked for me once.
This is one reason I say the leg should be dropped each year to clean and lube the splines.
