quicko: prepared to

Australians can use this phrase not only to mean prepared and ready to, but also just plain willing to.  Thus, you can end up with Australians saying they're "prepared" to do something that has required absolutely zero preparation -- for example, "I can't believe you're prepared to help me cheat on my test; I didn't think you'd do something like that."  Or the like, but I'm out of ideas.  Insert your own example here.
