M.I.A. - April 1, 1969 - S2-E22
Continuity mistake: In the beginning, when dressed in drag, Sam has a cigarette with a long bit of ash on it. He looks at his "reflection" and there is a short bit of ash on the cigarette, then it cuts back to him and there is a short bit of ash.

Factual error: Though this episode takes place on April 1st, 1969, a freshly-painted sign in the park contradicts the date. In the scene with the hippies in which Sam is disguised as a meditating guru, the huge sign just behind him touts the San Diego Centennial Celebration - in 1968. (00:16:00)
M.I.A. - April 1, 1969 - S2-E22
Continuity mistake: Near the beginning, when Sam is undressing and Al is telling him who he leaped into, in one shot Sam is taking off his beaded necklace and in the next his necklace is off and he's taking off his belt, but Al continues the sentence so no time passed during the cut.

Audio problem: When Sam, dressed as a guru, is talking to Al about Beth, Al calls the lawyer a "scuzzbag" but he mouths "scumbag." Guess it couldn't get past the censors.
Answer: In the finale, Sam leaps back to the episode "M.I.A." which is set in 1969. Originally, he failed to stop Beth from remarrying. However, the episode you're talking about, "The Leap Home", takes place in 1970. At the end of that episode, Al tells Sam that Maggie, the woman who took the picture of Al, finally got her Pulitzer Prize posthumously. But there's no indication when the picture of Al becomes public, or if Beth even saw the picture. However, if Beth did see the picture, or is aware Al is a POW, she's already moved on.
