This just might be nerdy statistics overload even for me. A group from the John Hopkins biostatistics department has created parodies of Sir Mix-A-Lot's Baby Got Back and MC Hammer's Too Legit To Quit. For your listening pleasure - Baby Got Stats and Too Logit.
The songs are in MP3 format, so you can put them on your iPod and play them over and over and over again. One play-through was enough for me, but clearly, it's only a matter of time before this biostat group hits main stream.
Update: Here's the video version for your viewing pleasure.
