blue vein steel The Flair Flop is an accepted part of his gimmick, in the same way that HHH being in full bury mode (like this) is part of his gimmick
Yellow Lantern Since there's no commentary, my guess is that this was a post-show match put on for the arena crowd and not televised. They tend to do goofy spots like this in those matches. They leave the camera running so they can use footage for funny moment compilations and such.
