Do you know any Idioms ?

I just talked to a dude about motorcycles, bike builders, bike shows, mechanics and about everything motorcycle related.  Everyone we chatted about, he had some type of "idiom" to relate me to how he felt about such doings . . .

- "Hey, It takes one to know one . . . "
- "Revenge is a dish best served cold . . . "
- "That's the pot calling the kettle black."

Huh, the pot calling the kettle black?  I guess here's how that one goes.  This pot and kettle are beside each other on a stove top.  This "pot" (which is very shiny and looks real polished, almost like chrome) calls the "kettle" (which is a dark, black and stained finish from doing all the work) . . . The pot calls the kettle Black.  I guess the kettle responds that, on the contrary, "It is "You, the Pot" who is Black, and you are seeing your own reflection on my shiny surface.  It's the kettle who intellectually outsmarts the "simpleton" pot who was eager to degrade the appearance of The Kettle, who plays a mind-game type trick on the pot and . . . Of coarse that gets the pot all pissed off . . . and they still hate each other to this very day !  * The photo of Cindy Crawford has nothing to do with this post.  She's just got that 80s hotness that most all younger women of today seem to lack a bit.
