Dr. Nerd is a member of the Barney Bunch. He is not to be confused with Dr. Neo Cortex. He's the world's second g*y*st scientist. He is a very swell scientist who collects s*m*n (he has g*y s*x with minor, mind you not underage, male M-san Bunch members) and uses it for his airship. He is probably Cortex's swell twin brother. Homer loves to call him and yell out "NERD!" He is also good friends with the R*tarded Hexbug, since they are both toys.
