1. "The Most Beautiful Girl in the Lab" - made at UCSF! This is a parody of Flight of Conchords' "The Most Beautiful Girl in the Room":
I love how creative scientists can get! :)
2. Parody of Lady Gaga's "Bad Romance", also pretty good though not made by scientists:
Edit: I just learned that the second video is by a cappella men-only choir "On The Rocks" from University of Oregon. It seems that university environment stimulates people to satire... :)
