Some people leave their jobs on good terms, keeping their friendships (and, of course, future references) intact, while others come up with clever ways to burn every possible bridge between themselves and their soon-to-be former employers. But Karen Cheng chose to combine the two, making a cute video of her rewrite of Don McLean‘s ‘American Pie’ to give her notice at Microsoft.

As she says in the song, Cheng, who spent three years at Microsoft working on Excel, is leaving to work for a startup in San Francisco. But she’s proud of the work she’s done and will miss Taco Fridays and drinking in the hallways with the developers (which, frankly, explains many of our problems with Excel).

This is not Cheng’s first Excel-themed song. A look through the rest of her uploaded videos reveals a two-year old clip performed in front of a collection of colleagues. Cheng sings “We all work with Excel spreadsheets” to the tune of ‘Yellow Submarine’ by the Beatles.

We wish her the best in her new career, and we’re also glad that she stopped at two verses instead of trying to re-write all of the original’s six stanzas. Then again, would it be too much of a stretch to make Bill Gates Satan instead of Mick Jagger?
