You might be a packrat if:
Instead of an address book, you have 30-50 business cards, bundled by a rubberband which originally came from a Broccoli.
Someone asks if you have TV Guide, and you wonder what year.
Once a year you wonder how long you are supposed to keep bank statements. Then tuck the box with the last 2 decades worth back under the bed.
You have pens from businesses that went out with the Carter administation.
On those first warm days of summer, you have a hard time deciding whether to wear your CHiPS t-shirt, your Charlie's Angels T-Shirt and whether either go with your Mork suspenders.
Your dot matrix printer finally needs a new ribbon... and you have 5.
