What's with this rule that April Fools Day stops at 12pm? Ugh.
Anyway, I work at a vacation company. Called in to a coworker as a texas (he's Aussie, had no clue

) and went over a $20k vacation for 20 minutes, thinking he was getting a huge commission. Then I went into how I needed a second booking for my mistress. I ended up in front of his desk at the end, took him some time to register what was going on
Also took out someone elses mouseball. He always has a lot of problems with his mouse, so it took him a while to realize the ball was missing. Also did the tape under a laser mouse and desktop screenshot to remove icons to another coworker.
All in all, nothing too crazy or anything that required real effort
