Lilleputthammer is an amusement park north of Lillehammer, Norway. It features a 1/4 size replica of a street in Lillehammer. (It has 4 stars on tripadvisor.) This video shows a bunch of Norwegian bodybuilders hanging out in Lilleputthammer. I have to assume this is from a comedy show of some sort. Though I want to believe these guys really do hang out there regularly because it makes them feel even bigger.
Especially this guy. He must be Gronkwegian.
