I'm pretty sure my Monday wins...
I started off the day nearly late for work because I got kicked by a deer.
The bastards squeezed into the pool area through the gap in the fence again, and I had to go chase them out again since they can never figure out how to get back out, panic, and then smash themselves silly on the fence till they knock it down. So I have to go down and very carefully open the gate and herd them out.
Except this time, one of the idiot walking jerky strips panicked and fell into the damn pool.
So I had to spend twenty minutes dragging the plastic pool stairs out of the shed in the back yard, tossing them over the pool fence, putting them in the pool while being mobbed by a handful of panicked deer, and then try to push the dumb thing over to the stairs with the pool net so it could get out.
As it charged past me out the gate, it kicked me in the meat of my calf.
I spent the day at work hobbling around, which just enhanced my foul mood while suffering through a hellish day at work.
Pro Tip: The guy who got kicked in his bad leg by a large herbivore probably doesn't want to spend his day repeatedly climbing a step ladder and standing on his tip toes to stir the crap in the big tank so we don't lose the prime on the pump - which isn't technically his damn job anyway.
