Never Gonna Give Your Teen Spirit Up

This video mash-up has been around for a while, dropping Rick Astley's "Never Gonna Give You Up" into Nirvana's "Smells Like Teen Spirit", but I only became aware of it recently. Seems to work out far too well. If I ever have the chance to sing "Smells Like Teen Spirit", I just might lapse into "Never Gonna Give You Up", just for laughs...
