irony of the day

wouldn't you expect a song about irony to actually include examples thereof? rain on your wedding day isn't ironic; it's actually considered good luck. a green light when you're already late? also not ironic. now, if the green light made you late, that'd be ironic. once you're late, a green light is meaningless. it's not even luck (good, or bad).
irony is the guy who gets shot, & credits his assailant w/ saving his life. seems he had an undetected cancerous tumor, which never would've been found if he hadn't been in the ER that day. that's irony.
