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.
Answer: Sam threw items off the raft to lighten the load, so it wouldn't sink, in doing so he made the raft less heavy. Which made easier to float with the currents, if it was heavy the raft would have moved slower and not moved so far.
Except that Al said that immediately after throwing stuff out of the boat four hours passed and it was shown that they didn't really move from where they were. They were still in the same spot. Forgot to ask this too. When Sam and Vanessa are stranded on the island, one of them, can't remember who, did something and when Al appears, he tells them that because of it, time had suddenly skipped several more hours and if the event hadn't been interrupted, they would have been rescued by a boat. So, what happened on the island that once again caused time to speed up? It seems kind of strange that time could move so quickly on the island, especially since it was still day time and it never showed any sort of changes like the sun or clouds moving.
