Classic was when Rico was on the turnbuckle preparing for a moonsault and Jeff Hardy was meant to push him off, Jeff must have forgot about it or something (probably the hash
) and Rico was there on the turnbuckle, repeatedly falling off BLATANTLY deliberately for about 20 seconds then you hear Rico clearly shout 'C'MON JEFF GOD DAMMIT!' This was at Royal Rumble 2003, opening match.
Another great one was at Valentines Day Massacre 1999, When Ken Shamrock was having an argument with Ryan Shamrock outside the ring, when it goes silent for a few seconds, then you hear and/or lipread Ken blatantly say 'Slap Me!' Sure as hell, after Ken says this, Ryan slaps him right across the chops!
There are plenty of others, just can't think right now...
