#2 Booker T was tongue-tied
Booker T, who's apparently now starting to get on Dave Meltzer's nerves, had a couple of noticeable bungles while taking up his commentary duties. The first occasion to highlight was this moment when he cracked up laughing after saying that Brock Lesnar will be fighting Brock Lesnar.
Book thought the idea of The Beast Incarnate fighting himself was uproariously funny, apparently.
Michael Cole faltered a couple of lines immediately before this but didn't let it derail him. That might have fed into Booker's outbreak of giggle fever. Also, while it's not highlighted in the above gif, Booker also claimed that Bo Dallas & Curtis Axel were both second generation wrestlers during their 6-man tag team match. The two are actually both third generation wrestlers.
