A male friend chats with you and says he is in a bad mood. He doesn't know what to say, how to tell a joke to make him happy.

A stutterer went to buy a drink and found that he only had fifteen yuan on him, so he asked his boss how much Coca-Cola was.

Stuttering: old ... old ... old ... old ... a board ... a bottle ... a bottle of coke.

The boss was so sad that he helped him with a bottle of Coca-Cola before he finished.

Stammer: How much ... How much ... (I think I finally finished)

Boss: eighteen dollars.

Stuttering: buy … buy … buy … buy … buy.

The boss was so sad that he opened it for him before he finished.

Stammer: I can't afford to buy ... buy ... buy.

The boss had to drink the bottle of coke by himself.
