Our national postal service outdid themselves yet again.

We all know that they're a bunch of legends - they delivered a special letter to Olympic medalist Annalise Murphy, and even miraculously delivered a letter to a cat in Galway. Yes, really.

And they went along with it...

Nice to see that they're always up for a bit of craic.
