woah woah woah, hang on, so you recorded the audio weeks ago so you could plan everything, so you spoke those lines, which means it's a planned line, so you knew it was going to happen so you COULD have recorded the footage from the original studio session, that "this microphone isn't even plugged in" was a gag you made weeks in advanced whilst talking in to a microphone that was plugged in,(reply>), That's the joke,(reply>), I'd also love to hear how many takes the "not actually a party" party scene took,(reply>), At this time of the year? At this time of day? In this part of the country? Localized entirely in this studio?,(reply>), Degrees of separation.  You have to think hard to appreciate the amount of prep they did for this. Must have taken absolutely ages.,(reply>), They didn't even have to take fifteen takes of the party scene but I like to think that they did.
