Ha ha! Yeah, I'd heard that one, too, in slightly different wording "only boring people get bored."
I may describe my day or week or any period of time as "boring", but by that I mean that nothing really noteworthy took place. I, personally, don't get bored.
OT: Sometimes when someone is talking to me I like to fake a yawn and say "you bore me" in a fake british accent. I can be a jerk! lol!
