What is the proper way to pray to Odin?

[Minimalist]

Odin has many names, e.g. the All-Father, the Terrible One, the God of War, God of the Hanged/Dead, the Wise One, and others. He's a pretty moody god and you never know how he'll respond to an unsolicited request, such as a prayer. How do you respond to a telemarketer or an aggressive salesman, like a Jehovah's Witness banging on your door at dinnertime? I believe the best way is to pray that he's in a good mood and then also ask for forgiveness.
