Let's hear the joke.
All of these have to be told light-hearted, as observational "jokes". Not like you are actually annoyed. You're just making light of a situation.
"I guess the bus is just never on time here, huh"
(Stuck in line at the grocers) "Friday evening rush-hour"
Same kind of thing with whatever you are observing, at the Doctor, in the gym, waiting for the light to turn, etc, etc.
It's all shit jokes if you can even call them that. But the purpose isn't to start a standup routine, it's to share a situation with a stranger and open up the floor to conversation. You are basically just indicating to a stranger: "Hey, I'm open for conversation", they can then choose to respond or just ignore the remark. Then you go from there.
Turd Ferguson; that's a funny name
"Your tax dollars at work"
Applies to almost any situation, really.
