Re: The WTF challenge!
Done something much like this myself recently. Vice grips didn't work, heat didn't work, cutting a slot and using an impact driver didn't work, yelling and screaming didn't work, easyouts didn't work, drilling didn't work (the s/steel just laughed at it's feeble attempt to cut).
...Until I was put on to using a carbide tipped drill bit. These look like masonary bits but are for metal and the like. I was able to drill the remains out by hand with a cordless drill and then I just needed to run a tap through the hole to clean up the thread. The secret to the carbide bit is that it doesn't drift off the hole and cuts like a hot knife through butter. My bolt was threaded into aluminium and the threads were left totally undamaged by the process so easy was it to control.
