Betty White took a stroll down Memory Lane on 'Late Night With Jimmy Fallon' (Weeknights, 12:37AM ET on NBC).

The veteran actress took on host Jimmy Fallon in a game of 'Password.' White was a frequent guest on the original 'Password' network TV game show, which aired in the '60s and '70s.

In fact, White's involvement in the show went further than just guest-starring on it: She married "the man in the middle," Allen Ludden.

'Password' host Ludden became White's third husband in 1963 and they remained together until his death in 1981. In fact, in a touching moment, White told Fallon that her appearance on his version of 'Password' marked what would have been her and Ludden's 48th wedding anniversary.

So, after a such a lovely story you'd have thought that Fallon would let her win, wouldn't you?

Well, you'd be wrong. Fallon showed no mercy to his guest: He and his partner went on to thrash Team White 15-0.
