Give it away, give it away now!

Hi y'all! As per my most recent post I've just sent 4 books from my personal collection to a very dear friend to get her hooked on the Disc (as it were! )

My question is how many of our lovely lot here are so enthusiastic (or careless?) that you've given away your own Discworld books to others, usually followed by the statement "You really have to read this! Really! Trust me, it's great!!" or something (hopefully rather more persuasive! ) like that?

Come on, 'fess up! I've probably given away a whole series like that; who else does this???
