As heard in Spongebob, "Happy Lief Erickson Day! Hinga dinga durgen!" Obviously poking fun at the speech of the vikings.

From the episode "Bubble Buddy" of the francize SpongeBob SquarePants. SpongeBob (The main character) wakes up, while wearing a fake ginger beard and Viking hat. Then sits up in his bed then says directing to the audience "Hey everybody it's Leif Erikson day. Hinga Dinga Durgen!". The line 'Hinga Dinga Durgen' teases the way Vikings spoke.

An expression commonly used in Old Norse to express glee.

Swedish for, "Hang things." Used in the Lief Erikson day spongebob episode to poke fun at viking schpeek
