I woke up to a fun tweet in my timeline this morning:
@ismh Maybe one of your Macs are eligible? https://t.co/ynjmkC601k

I had no idea this existed. In short, some Macs sold between 1992 and 1996 came with free telephone support as long as you owned the machine. In 1997, Apple tried shutting it down, but got hit with a lawsuit.
The best part? The phone number still works.
