A man seeks enlightenment as a Buddhist monk

So he joins a Tibetan monastry and takes a vow of silence whereby he is only permitted to say two words every five years.

After five years he appears before the elders and they ask him what he wishes to say. He says, "Food's cold."

Ten years later he appears before them again. The elders ask him what he wishes to say and he says, "Bed's hard."

After fifteen years he appears before them again. When asked for his two words, he says, "I'm leaving."

"About time," says the head monk, "All you've done since you arrived is complain!"
