Sam: Leaping about in time, I've found that there are some things in life that I can't change, and there are some things that I can. To save a life, to change a heart, to make the right choice. I guess that's what life's about, making the right choice at the right time.
Sam: I can't have a life. All I do is live someone else's life. I right their wrongs, I fight their fights - geez, I feel like I'm Don Quixote.
Sam: Do you have to sneak up on me?
Al: I'm sorry. What do you expect a hologram to do? Knock?
Al: Don't do anything I wouldn't do. And if you do, take pictures.
Al: I went over to check out the cheerleaders. Oh, Sam. There was one little girl who had these pommelos, man.
Sam: Pommelos are grapefruit.
Al: Pommel - that's my point.
Sam: What is she doing in Syracuse?
Al: I bet a lot people ask themselves that question.
Al: Their only desire is for you to pamper them, and play with their.
Sam: Al.
Al: With their hair! Their hair.
Al: Well, we been having some difficulty. Ziggy, he's, uh, going through mood swings. I think we need get a girl computer put it right next to him, one with a nice set of hard disks.
Sam: You would.
Sam: Say something to me in Spanish.
Al: Uh, tu casa o mi casa.
Sam: My place or yours - Al.
Al: Don't tell me, let me guess, you've been invited to a costume party and you're going as a baked potato.
Al: If we knew the unknown, the unknown wouldn't be unknown.
The Devil (as Al): What gives you the right to leap about time, putting right what I made wrong.
Sam: I'm just trying to get home.
The Devil (as Al): Well, you're not going to make it.
Al: Oh, well, almost all animals can see me. But you know, there must be something weird lookin' about me, because I seem to intimidate them.
Sam: Maybe it's your clothes.
Chosen answer: Per the Quantum leap page at http://www.scifi.com/quantum/episodes/season5.html. 8 August 1953: An enigmatic leap lands Sam in a Pennsylvania tavern, as his own grown self on the day of his birth. As Al and Gushie work frantically to locate him, Sam befriends a wise bartender (popular character actor McGill, who'd appeared in a different role in the very first "leap") and a group of coal miners. As a host of familiar-looking faces pass through the bar - with different identities than Sam remembers - Sam ponders his life of leaping with Al the bartender, who tells Sam he controls his own destiny. Pressed for more, Al the bartender simply shrugs and says, "Sometimes, 'that's the way it is' is the best explanation." Sam realizes he must right at least one more wrong before he can go home, and leaps back to tell Al Calvavicci's wife Beth (from "M.I.A.") to wait for Al, who will survive Vietnam and come home to her. The closing title cards state that Beth and Al have four daughters and will shortly celebrate their 39th wedding anniversary ... and that Sam Beckett never returned home.
