I am sorry that I have abused you by not sharing something I thought up that I think it discordian gold. Take a cliche` and keep the structure of it but change it slightly to point out it's faults. Examples are below.
"When you assume you make an ass out of you and me"
"When you make an assumption you make and ass out of you and umption"
"When guns are outlawed, only outlaws will have guns"
"When laws are outlawed, only outlaws will have laws"
Please add your own.
