Actually he popped up yesterday in my Springfield. First time in three months.

Really? That's kind of surprising. I had assumed that they'd mothballed him again; the last I saw him was around the time of the Halloween update. Frankly, Bob's appearances are so sporadic, I wish they would just do away with that feature (since they can't seem to get it right) and instead make him a regular character.
