Uh oh! I think this is rapidly turning into a random idea thread. And I like it!
How about the requesting team...
"Someonce once said telling Chuck Norris that a roundhouse kick is not the most efficient way to kick people was the biggest mistake ever made. Here at team YYYY we say not picking team XXXX is!"
Or even funnier
"With the help of team XXXX maybe our alliance can be as awesome as Andy Baker!"
"Will the real team XXXX, please come up, please come up?"
Or even just sound like the MC
"Team XXXX would like to invite a team hailing from (team location), (team name), (team number)!
