Bunter Hund (untranslatable pun)

Einer der beiden Partner, die gerade den ersten Preis für die hässlichste Weihnachtsdeko aller Zeiten gewonnen haben.
One of the two partners who've just won first prize for the ugliest Christmas decoration ever.
As to the title: If you call someone "bunter Hund", it means he/she sticks out like a sore thumb, but the pun is lost, as the literal translation is "colourful dog", which wouldn't make sense in English.
