Gary the Unicorn

Gary the Unicorn was a unicorn that was in AABF14 Simpsons Bible Stories He was in Marge's Dream, where she dreams that she's Eve in the Garden of Eve, Homer's Adam, & Flanders is God. Gary dies & Flanders(God) gets angry.

Curiously when Ned Flanders (as god) prods Gary and queries "What have they done to ya Gary?" he sounds remarkably like the Character Spongebob Squarepants especially using the name Gary, however this Episode was produced before Spongebob aired, this Episode also aired 1 month before Spongebob originally aired in May 1 1999

This counts as a coincidence and not an intentional reference.
