Ew! That was gross, Wah!
There's wart removing medicine out there. I think it's called Compound-W. I had some warts on my fingers (haha, yes, on the middle finger too) and I used Compound-W to get rid of it. Works pretty well.
Edit:
Whatever you do, don't try to cut it off with a toenail clipper! I tried that, and it bled like crazy, and the wart came back, bigger and uglier.
