A man enters a monastery and takes a vow of silence. This can only be broken every 10 years and then the monk can only say 2 words.
After 10 years he is allowed to say his 2 words. He says, 'food, bad'. Another 10 years passes and he's allowed to say another 2 words. He says,'bed, hard'.
Another 10 years go by. He's been there 30 years now. He's allowed to say 2 words again. He goes to the leader of the monks and says,'l quit'.
The other monk replies, 'l'm not surprised. You've done nothing but complain since you've been here!'
