In the advert where the main guy is looking up Best Man's speeches on the internet.... I don't understand, when he says "..and you could hear him in Nairobi.." (during the actual wedding scene) no body laughs and his girlfriend and children all cringe! Am I missing something here, or is the idea that we aren't supposed to know what it means and why it isn't funny?
I may be wrong but I think he's referring to the couple's sex life which is funny until he brings a photo up on Powerpoint to back up his claim (but we don't see that). ???
