I've found tons of evidence, and heard countless stories of ppl seeing them under their beds and out their windows, but I just need to ask. Evidence includes things like: They have greeting cards with records in them, and on the back they say "Voices by: Authentic chipmunk voices featuring Ross Bagdasarian" The chipmunk adventure gives credit to Siri D (Dahrma) Galliano (a fitness trainer) For being the "Chipmunk Masseuse" on the back of the insert for the CD "Still squeaky after all these years" (1999) is a picture of Ross Bagdasarian Sr., apparently in a recording studio with two mics, and two real chipmunks on a counter/table in front of him. below this is "A special thanks to ross Bagdasarian Sr. for teaching three chipmunks how to sing" What do you think? I have more evidence, though. =P
