I learned a couple useful "tricks" as an investment banker.  First, when you are going to a company to make a pitch, ALWAYS check the sign-in book to see who has been there before you.  Second, NEVER really sign in as yourself. Finally, NEVER (and I mean NEVER) talk about a deal in a taxi cab, limo or town car. 

I have no idea if this actually happened, but it is definitely possible. A directly quote from the Skype blog: "Something wacko — the news was apparently known to some New York taxi drivers way before the announcement. I kid you not — the week before the announcement, we received a comment in our Customer Support from some NYC taxi driver about eBay acquiring Skype, and we downplayed this as a rumor, which is what it still was for us at that time. The taxi driver replied “look gentlemen, you may disregard it all you want, but I know the facts since I just gave a ride to some eBay execs who discussed exactly what would be happening”. Can’t validate if the story is really true, but looking back, it turned out to be true and funny nevertheless."
