Okay, go ahead and start the flaming.......but try a can of Fix-A-Flat. I have had very good luck with that stuff. The makers of it have improved it greatly during the past few years and it should plug anything smaller than a quarter-inch hole.
Make sure your tire is fairly warm (at least a few miles of driving) and that you are near an air compressor. Turn the wheel so that the valve stem is at the bottom of the tire, empty the whole can into the tire and then put a few pounds of air into it - at least so it doesn't look flat anymore. Drive it for a few more miles, then go back to the air hose and inflate it to proper level. Check it again in a few hours to make sure that the seal held up.
Keep an eye on it and it should be okay. Of course, if you off-road a lot or drive at extremely high speeds....spend a few bucks and get it patched from the inside (better than a simple plug).
