Wade sez, "Sun Microsystems has posted extremely pointed OpenOffice.org ads on the sides of transit buses that serve Redmond. Slogans include, 'Stop giving a bully your lunch money,' 'Compatible with expensive, closed, memory-loving software,' and 'Prehistoric reptilians welcome.' Booya!" Link (Thanks, Wade!)
Update: Creede sez, "Just a quick note from a guy who takes the bus to Microsoft on a regular basis. I haven't done an in-depth survey to confirm that this is the case, but it certainly seems like those OpenOffice ads *only appear on bus routes specifically going to the Microsoft campus.*"
