Funniest thing a guy ever left behind ... is ..

Ok .Ladies....what is the funniest thing a guy left behind... at your place ..... After he came ... Then left ??? I found a valuable knife ... recently . I don't know what to do with it. I don't know who it belongs to . I had 2-3 clients that day . I've got a Nike cap . A pair of reading glasses . If it's wallet or keys - If i find something left behind - I rush out and give it to them . I know you guys and girls have some great stories here . . . .i want to know . And Old Sarge you can have the Knife if you come collect your 10 bucks . ha . . . Naughty . J
