I got this from Why are you stalking me and thought it was hysterical! also it's Friday and i am way to tired to be funny for myself...or just plain lazy works too!
I was confused when I heard the word service used with these agencies:
Internal Revenue service
U.S. Postal service
Cable TV service
State, City, County & Public service
This is not what I thought service meant. But today, I overheard two farmers talking and one of them said he had hired a bull to service a few cows. BAM!!! It all came into focus. I understand what all those agencies are doing. Now you are as enlightened as I am.
