bookmobile vs. boobmobile
We know which one would win as far as da number of folks gathered around it. :P
Y'know, da concept of "bookmobile vs. boobmobile" might not be such a crazy idea, after all --- if they had one or more chesty chicks operate and staff said tomes-stocked bus, and promised guys dat dey would each get to feel up said well-endowed cuties for a few minutes in exchange for every book dat dey read, local literacy and readership would likely skyrocket!
