"Houston, You Have A Problem"
Which reminded me of my all-time favorite. Back in the early days after Indianapolis stole the Colts (in case I haven't apologized to Baltimore recently, I'm sorry; as much for keeping the name as swiping the team) it was fairly standard for teevee announcers to slip up and say "Baltimore" two or three times a game. They usually caught themselves at it. But when Joe Willie Namath came to town he must have said "Baltimore" twenty times, and never looked back once. I happened to go to the next game were he was in the booth, and hanging from the second deck was a bedsheet reading:
"Indianapolis Welcomes Broadway Jim Namath"
which almost made watching the Ol' Dolts lose by thirty worth it.
