Brilliant or Bonkers?

I can't decide if this is the most brilliant birthday card I've ever received or the most bonkers. It's a tough call:

(the text inside reads: "Also, unicorns would have teats and let total strangers yank on them. Hope you get a frothy mug of something good on your birthday.")

Brilliantly Bonkers? I think that's what I'll go with. But it still made me laugh so hard I nearly cried.

What do you think? Brilliant? Bonkers? Brilliantly Bonkers? Or something in between?
