#4 Mark Henry vs. CM Punk

CM Punk and Mark Henry had a mini-feud for the WWE Championship in 2012 on RAW. Henry won two matches by disqualification, while the third match was won by Punk, helping him retain the title.

The two had faced each other a few times before that, when they met in ECW. CM Punk and Mark Henry were also involved in a couple of tag team matches in WWE.

Him and Mark Henry I think I always tried cracking up the most.
