I had an “aha!” moment last night while watching TV.
Commercials were on, and right after a truly horrific political ad for a complete idiot who should never have even been allowed to graduate 1st grade, I spotted the exact replica of Sibling 10.
It was a Geico commercial.
You know, the ones where you see some random scene and then two guys are on a wierd little stage playing a banjo and guitar and saying how happy people with Geico are?
This particular commercial was a scene of a slinky going down an escalator.
Sibling 10 is the slinky.
