To all the biologists out there

Have you ever heard of Ron Laskey and his collections of songs called "Songs for cynical scientists"?
They are just hilarious and so in touch with the lfe in a lab.
We have bought the album a few weeks ago and just can´t sop playing them in our iTune at work!

Well done Ron!
