Well, this just happened...
Me: Hi, I'd like to ship this item and I'll need it insured for $XXXX.
UPS guy: What is it?
Me: It's a comic book.
UPS guy: *Calls someone on the phone. Hangs up.* I can only send a comic if there's a certificate of authenticity.
Me: Well, it's graded by a company called CGC. They grade, authenticate, and encapsulate collectibles.
UPS guy: Then I'll need to see inside the box to confirm.
Me: *blank stare* Fine. Open it up, as long as you pack it back up again.
UPS guy: *opens box* What is this?
Me: It's a graded comic book.
UPS guy: I need a certificate of some kind...
Me: See that barcode there...
UPS guy: No, I need a signed certificate of authenticity.
Me: *pauses* From who?
UPS guy: I don't know, someone.
Me: Like...Stan Lee?
UPS guy: Is he a comic specialist?
Me: Thank you, this has been fun. I'll head over to FedEx.
