 Nielsen (and George Kennedy) were hired as sleuths to unravel the mystery of the Undertaker, who had disappeared at January's Royal Rumble event.At SummerSlam 1994, in a "Naked Gun" parody, they were hot on the case (in fact, they were standing on a case).Although they did not find the Undertaker, the case had been closed (the literal case had been shut), thus they solved the mystery.
