That's funny. I say that "I want one" line all the time, but I forgot where it came from. I also like the way he says, "Oh, it's you, Charlie." Also priceless is the line he says to Sela Ward when he first meets her: "I was just protecting my balls, as I'm sure you, at one time or another, have protected your own." Great stuff.
"She's, like, a biscuit older than me..."
I love when Gleason asks Hanks, "Are you with a woman ? Anyone YOU know ?"
Also, the whole duck hunting scene and the scene when Basner first meets Sela Ward. Wow she was gorgeous - and so bad and good at the same time....
The scene where he tells the client off is stellar Hanks; and of course, the scene with Gleason in the hospital after the operation and the "You were the last person I ever thought".....that always, always makes me cry.
