A guy becomes a monk and when joining, the monk boss tells him that he must take a vow of silence and only gets to say 2 words at the end of every 5 year period. He agrees.

5 slow years pass and the monk is asked if he has 2 words to say. "Bad food" he replies.

Another 5 years pass and again, he's asked if he has 2 words to say. "hard bed" he replies.

Another 5 years pass, and when asked, he replies "I quit".

Monk boss says "that doesn't surprise me, you've been complaining since you got here".
