A Mentalist left the Britain's Got Talent 2012 judges stunned this week with a mind reading trick.
Colin McLeod appeared in front of judges Amanda Holden, David Walliams, Alesha Dixon and Simon Cowell, along with their autobiographies.
Asking the panel to select a book, page number and line, Colin then had Ant and Dec join him on stage to pick out the longest word from the line on the page in the book that the judges had chosen.
Wowing the audience and judges, Colin proceeded to reveal the same word had been written on his bottom the whole time!
