My favorite Serenity Prayer parody:
"Grant me the Serenity to accept the things I cannot change,
the Courage to change the things I cannot accept, and
the Wisdom to hide the bodies of those people I had to kill today because they pissed me off.
And also, help me to be careful of the toes I step on today
as they be connected to the ass that I may have to kiss tomorrow.
Help me to always give 100% at work
12% on Monday.
23% on Tuesday.
40% on Wednesday.
20% on Thursday.
5% on Friday.
