Mallam Osman lost his cheque booklet and went to bank after 2 weeks to report.
Bank manager: But I warned u to be careful with your chequebook mallam, cos anyone can forge your signature.
Mallam: I am not a fool. I have already signed all the cheques, so they won't have space to forge my signature..
