4 muscles

Grant me the serenity to accept the things I cannot change, and the wisdom to hide the bodies of those I had to kill because they pissed me off.
And also, help me to be careful of the toes I step on today, as they may 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.
And help me to remember: When I'm having a really bad day, and it seems that people are trying to piss me off, that it takes 42 muscles to frown and only 4 to extend my middle finger and tell them to bite me.
