Once an old man was sitting in the park reading book “Learn Java in 21 Days”. A passer by saw him and asked, “U are such an old man, why do you bother to learn Java?” “I have heard that the communication language in heaven is Java and so after my death when I will be in heaven, I don’t want to face any communication problem.” the old man replied.
“But how come U are so sure that U will be in heaven? U could in hell also.” he asked. “Ya, it doesn’t matter then …. I already know COBOL”.
