The one which immediately springs to mind for me is vs the Nexus, when he took a DDT onto exposed concrete, popped back up and beat 2 men to win the match. According to Jericho and Edge, he booked the ending to that match himself.
Or Royal Rumble 2008 (?) when he was supposed to be injured for something like 8 months, miraculously healed up after what felt like 3 weeks, entered at number 30 and won it.
2007-2010 were some dark times.
