The running joke is that The Undertaker's entrances are just as long as his matches. And though that's stretching it a bit, it's closer to the truth than most of us would care to admit. But at Wrestlemania, the Undertaker's entrances are always an elaborate spectacle, and they're as impressive as the best promo from Bobby Heenan. The production crew pulls out all the stops; there's stage smoke, and druids, and flames. This particular shot is from Wrestlemania XXIX. Why is the Undertaker the greatest WWE superstar in history? This photo makes a pretty compelling case.
