Getting some ASS

This is the Nr. 2 ASS Building, containing the "ASS Clinic" (ASSクリニック) which offers counseling (カウンセリング). I was tempted to go in and asked if mine "looked big in this", and also where the Nr. 1 ASS Building was, but it was late at night and they were closed.

Seen somewhere in the vicinity of the western Yamanote line, probably in Shinjuku, in 2006.
