#2 Survivor Series 2005
The year 2005 saw one of Randy Orton's best feuds in WWE - the one against The Undertaker. The duo first faced off at WrestleMania that year with The Deadman winning and taking the streak to 13-0. Taker and Orton faced each other once again at SummerSlam. Orton won the rematch with a little help from his dad 'Cowboy' Bob Orton. This led to a handicap match at No Mercy with Undertaker facing both Randy Orton and Cowboy Bob. The Ortons then set the casket on fire.
The Undertaker made his return later that year at Survivor Series, emerging from a burning casket while Orton was celebrating with the SmackDown roster after winning the tradition 5-on-5 Survivor Series match. Orton's facial expressions as the casket was brought out by the druids were just perfect and this is still one of my favorite Randy Orton moments. A bolt of lightning then set the casket on fire and the Deadman emerged from it. He proceeded to lay out the entire SmackDown roster as Orton scurried away and watched in horror from a distance.
This led to a Hell in a Cell match at Armageddon the following month, where The Undertaker beat Orton.
