Tommy is an unemployed mechanic who spends most of his time in a bar (Trees Lounge) in a small blue collar town. He seems to always be thinking, "If only X then I could stop drinking".

Tommy: Everybody's fucked up, but nobody wants anybody else to think they are, but everybody knows they are anyway.
[about having another glass of whiskey]
Vic: You're a weak man.
Tommy: Yeah, I know. That's why I drink it straight. The ice cubes are too heavy.
Tommy: He saved my life once.
Debbie: What, he was gonna kill you but he changed his mind?
Tommy: If I win, I get to take you home. If you win, you can go home with me.
Crystal: What kind of deal is that, huh? I don't know it doesn't make sense to me.
Tommy: It's a good deal. It's a good deal for me!

Tommy: I coulda been somebody, instead of just an ice cream truck driver, which is what I am, let's face it.
Debbie: Who was that, Jerry Lewis?
Tommy: Jerry Lewis? You thought that was Jerry Lewis?
Tommy: I know, but now I'm even worse. I don't know what I'm doing. I just, I, I just feel like... I don't know what I feel. I don't. I don't feel anything. Except lost.
Tommy: Hey Bill, did - did you ever kill anybody?
Bill: [slurred drunkenly] What kind of an asshole question is that?
Tommy: I mean, in uh, Korea.
Bill: What "career?"
Jackie: Billy, Stan got new glasses.
[to Stan]
Jackie: Show him your glasses.
[to Bill]
Jackie: He don't like 'em.
Stan: Get ready, Bill.
[puts glasses on]
Bill: You look like an idiot.
Stan: Go fuck, Billy!
Tommy: No, Jerry is allright. Saved my life once.
Debbie: What, he was gonna kill you but he changed his mind?
Tommy: He's a little old man. Can't you take some of the wrinkles out? You've given birth to Mr. Magoo.
Marie: You don't go to work every day. You go to a bar every day.
Harry: Can you help you?
Tommy: Yeah, I was in here last week, I left my number. I was just wondering if you found a mechanic yet.
Harry: No, not yet.
Tommy: Because I'm available, I mean I know you're probably still looking at other possibilities but I can start anytime.
Harry: I remember you. Where's your car?
Tommy: My car?
Harry: Yeah, when you drove away from here last week your car stalled out down the block, it took you 25 minutes to get it started.
Tommy: I know, it's a piece of shit. But I've got it running pretty good now.
Harry: So how come you're on foot?
Tommy: Just felt like walking.
