Santa lost his cheque book

Santa lost his cheque book.
He decided to go to the bank after two
days
to report.
The Bank manager said to him, "But I
warned
you to be very careful with your
cheque book
because anyone can forge your
signature."

Santa replied, "I am not a fool Sir, I
have
signed all the cheques already, so,
they won't
have space to forge my signature!"
