Dancing penguins invade Russia's subway system to offer Irn-Bru and be weird. Because weird is the Irn-Bru thing, remember Grandad 1999, the red heads & culprits in 83, and that lovely Sing Song, lets not forget that playboy at the pool '05, and how granny travels. To teach Russians how to drink Irn-Bru like a true Scotsman*, penguins are the ambassadors. Irn-Bru gets you through, mate. Just hang in there through the weird.
* there is no true Scotsman.
