I didn't know much about Stockholm, either, so I had to hit the ol' Google for some places of interest. And that "ABBA Museum" is real... I'm just surprised it took them this long to put one together, having opened only this year. (Actually this is one of my favorite Swedish exports.)
TRANSCRIPTION COURTESY OF JOSEPH HOUK - [BG and MG are on their "Excellent Adventure" – this time in Stockholm at a coffeehouse named Café Rawk] (BG) "What an awesome little café, Matt!" (MG) "Yeah, a friend of mine told me about it… So, what do you wanna do first here in Stockholm?" (BG) "I don't know… I've never been here before. All I know about Sweden is 'Ikea' and crazy, cheesy pop music." [A familiar barista appears – speaking English!] (Imy) "Oh, you silly Americans. There's plenty of things to do in this great city! There's the Palace, Sergels Torg, Moderna Museet, Gamla Stan and the Gröna Lund Amusement Park!" (MG) "See, Beth? Stockholm's full of cool stuff! Thanks for educating us, uh… [reading her nametag, not sure how it's pronounced] Imy!" (Imy – from the webcomic of the same name, by the way) "You're welcome! It's pronounced 'Eemee', by the way." (BG) "You must've lived here all your life, hun?" (Imy) "Actually I came from New Jersey. Been here about six years or so. Also, there is a cool 'Abba Museum' that just opened up in Djurgarden!"
