These are not My Pants

Bobby- Hey nice pants! They're little tight but nice.
Billy- Yeah I just got them.
Bobby- So they're new?
Billy- I'm not sure...
Bobby- What? how can you not know how old your pants are?
Billy- They're not mine... I just... well, found them. So I don't know if they're new or old.
Bobby- So you found these pants and you just put them on?
Billy- No! I cleaned them first. You don't think I'd put on some random guys pants without washing them do you?
Bobby- Wai-wai-wait! If these pants aren't yours then who's are they?
Billy- I dunno. I just found them and it turns out they fit... somewhat.
Bobby- You can't just take pants! where did you get them?
Billy- Do you remember the huge accident that happened just outside of town?
Bobby- Yeah who could forget something like that? I heard there were twelve vehicles involved!
Billy- Yeah well I was stuck in the traffic behind the accident that day so I got a nice view of the whole thing. Turns out a laundry delivery truck had been knocked over, and I guess it lost some of it's cargo. And as I drove by I noticed a pair of pants that seemed in fine condition. So I pulled over and picked them up. simple as that.
Bobby- So you took advantage of the confusion during a catastrophe and stole a pair of pants?
Billy- Well if you look at it that way then yes. I mean they're nice though, aren't they?
Bobby- that's beside the point. people were hurt in that accident! And you had the heart to rob a man of his pants!
Billy- It's not like I took them from one of the crash victims. The guy could have been anybody. But they're really nice you yourself said so earlier. Look I even got you a shirt.
Bobby- ... Really?
Billy- Yeah, here. I think you could bleach the tire marks out. Just make sure the whole load is white.
Bobby- Yeah sure. wow that's nice. Here let me try it on.
Billy- nice... very nice.
Bobby- Aw thanks man!
Billy- Wait so what were you saying just now?
Bobby- Uh... I dunno...I guess I forgot.
Steve- Hey nice shirt! I like the tire print.
Bobby- Yeah well it's vintage... ish.
