Actually, knowing the words to this song is grounds for divorce in most countries

1.  Why did two twentysomethings pick one of the most blatantly twee songs of the 1980s as "their song?"  Seriously, this is one of those ear-bleeders that had anyone with taste frantically twisting the dial of their Sony Walkman the moment the first chords made it identifiable.  "Our song?"  Ugh.

2.  Moron doofus thoughtless choad sharing a romantic moment with his two best friends- his girl and his phone.  Check.  Seriously, what kind of douchenozzle can't put his f---ing phone in his pocket during a dance?  It's called addiction, buddy.  Get help for it.

3.  Girlfriend asked boyfriend if he remembered this was their song- she didn't ask him to sing it, and once he starts to, we can certainly understand why.  I guess that's part of the joke- hey look people, not only is this guy thoughtless (can't remember* he and his girl have a song) and rude (holds his phone in his hand during a dance) but he has the worst singing voice since that guy screeching "This Magic Moment" in that Google ad.  Wow, what a great catch, lady.

*Or maybe he's just trying to forget that his girlfriend picked out this truly atrocious, cloying lump of decaying gush which really should have been left in the dumpster thirty years ago.
