10. Giant Gonzalez - WrestleMania 9
A massive human botch-machine, Giant Gonzalez's clash with the legendary Undertaker is renowned for being generally awful, rather than one particular incident standing out. The biggest botch committed was perhaps by whoever booked the match, especially as Undertaker's customary WrestleMania win came via DQ - after being rendered unconscious by a chloroform soaked rag.
