Just in case you were interested (from http://espn.go.com/page2/s/list/2004nflplayoffgames.html):
6. Merry Christmas, Miami! Dolphins 27, Chiefs 24, OT (AFC semis, Dec. 25, 1971)
At halftime, the game was tied, 10-10. Back and forth it went in the second half: Chiefs up 17-10, Dolphins tie it; Chiefs up 24-17, Dolphins tie it.
But it looked like the Chiefs had it won when Ed Podolak, having one of the greatest individual games in NFL history, returned a kickoff 78 yards to the Miami 22, putting Kansas City in field goal position with little time left. But Hall of Famer kicker Jan Stenerud missed wide right from 31 yards.
The first OT period passed with only two real scoring opportunities, a blocked Stenerud attempt from 42 yards out, and a Gary Yepremian miss from 52 yards. Finally, midway through the second OT, Yepremian hit a 37-yarder for the win. The longest game in NFL history -- 82 minutes, 40 seconds -- was over.
"It was a horrifying experience, because one break is going to be the game" said Chiefs QB Len Dawson of the overtimes.
Podolak's great performance is often forgotten because the Chiefs lost (their only home loss of the 1971 season). He scored two TDs, caught eight passes for 110 yards, rushed 17 times for 85 yards, and returned three kicks for 154 yards.
