I want a drunken Austria at a party or festival, messily eating snacks/cake/barbecue etc, getting sauce/chocolate/icing all over his face, spilling beer on his cravat, and not caring. Has to be of his own free will.

Bonus 1: Prussia thinks it's hilarious and encourages him.

Bonus 2: Hungary cleans Austria up and soothes his hangover/tummyache.
