Going to watch a TV show you've recorded/Tivo'd & it's not there.
Sitting next to someone on a plane who has bad gas. And covers their mouth when they cough, only to have it blow out the side of their hand & into your face anyway. Repeatedly. Thanks guy.
Being at work on a kickass fall day (sunny & 70) but seeing the forecast for the upcoming long weekend you've taken off (rain, daytime highs in the 50's, wet snow at night.)
