Toronto has a lot of rules about how to ride the escalators. If you don't follow them Torontonians get really angry about it.
I also find it funny that it reads a bit like a code of chivalry. Pregnant women, elderly and disabled persons are exempt from the rules... and it admonishes people who are in a hurry and get in the way of everyone else when they don't follow the rules.
In addition the start bit sounds a bit like the lines from Fight Club - and that is always humourous.
