I thought I had already posted on this, but apparently I simple shared the news with friends via e-mail.
Jonathon Coulton is funny.
My first experience with him was the song that GlaDOS sings at the end of "Portal". I went looking for more of his stuff, and found quite a bit.
For one year, he did a Podcast called "Thing a Week" where he did a new song each week. Lots of them are good, but he averaged one really great one each quarter.
An a capella version of "We Will Rock You/We are the Champions"
A song from an office zombie "re: Your Brains"
A programmer's lament "Code Monkey"
A great mash-up of the Beatles and Chicago "When I'm 25 or 64"
He has other songs and albums out as well. "IKEA" is a giggle-worthy.
So check it out. "Thing-A-Week" may still be available on iTunes. Just search for Jonathon Coulton.
