Hidden Agenda by Lee Earl: the spectators just thinks of the word and you get it right!

A very strong book test in which the spectator read a few random words form a book and then thinks of a picture. You then reveal your drawing which is an exact match!  Seems absolutely impossible. Then you toss another book to a spectator and ask him to find a word and just think of it. You write a word beneath the drawing and when the spectator reveals his word it is an exact match! For the finale you suggest his first word was too easy and ask him to find another.  Again, your correctly reveal his word! Never used!
