It's time to pay the bills......
Nothing odd about this at all within the context of the Toobworld Dynamic. It's just another slice of life during prime-time.
It's just two guys in some back alley who were approached by a disturbed individual. And that oddball had a fixation on either Little Lord Fauntleroy or Buster Brown shoes.
In fact, I think it could be that he was a cosplayer at the San Diego Comic-Con who just happened to stumble across the other guys while on his way to the convention hall.
Looked at with that sort of splainin, it almost seems mundane.
But yeah.... still pretty weird!
