A man goes into a bank with a gun and demands money.

Once he is given the money, he turns to a customer and asks:

Did you see me rob this bank?

The man replied:

Yes sir, I did.

The robber shot him instantly.

The robber then turned to a couple standing next to the dead body and asked the man:

Did you see me rob this bank?

The man replied:

No sir, I did not, but my wife did.

MORAL:

When opportunity knocks, make use of it…!
