How do you say 'how dare you' in Chinese?

This example is like is said in more of a joking way, like "oh yeah, you would dare to do that?" (sarcasm usually laced in)

你怎麼敢?

Nǐ zěn me gǎn

你 = you

怎麼 = how

敢 = dare

An alternative and more common way would be:

你居然敢

Nǐ jū rán gǎn

However, this is usually said when the action has already been done and is in more shock. This is the translation to "how dare you!?!?!"
