AT-5000 Auto-dialer

From Wikisimpsons

The AT-5000 Auto-dialer was an invention of Professor Frink and was the Professor's first pet.

Its original purpose was to inform children of snow-days, however, it fell into the hands of a bum who used it for telemarketing. Once he was arrested, Homer soon aquired it and used it in a money scam. He was stopped by Chief Wiggum.

One of the Auto-dialer's features was the ability to roll on wheels. Frink used this to make the Auto-dialer come to him, but it was stopped by Homer who removed the wheels.
