Puncturing on the inside of the tube? You might have a metal sliver stuck in the tape. Happened to me once, less frustration to just replace the tape. What is it, about $4. Also check the inside walls of the rim for burrs.
Oh, I remember the rim tape incident. Or rather the absence of rim tape incident. New bike, three miles from home. FLAT. Begin repairing. Hmmm, something looks wrong. Oh, shouldn't there be some rim tape!!! Not amused and let the bike shop know!
