Don’t try to make small talk with them. Instead, have some fun messing with them.
Go and stand nearby and make it look as if you’re observing them, when they look your way pretend to write something down and then go back to observing them again. After a while make a phone call and as you walk past say something like, “Pretty unremarkable bunch of people, they really could all stand to be redistributed…” or something along those lines.
This is a good activity if you’re a sociopath, if you’re not, I dunno, maybe find the ugliest of them and offer to buy them a drink?
