While working at a company that makes an online real estate listing and search platform, I added a Simpsons easter egg. If you searched for 742 Evergreen Terrace in any town named Springfield, the app would load a Simpsons-esque webfont, all text would be rendered in it, and the color scheme would change to yellow, orangered, and blue.

That was easy.
Yeah, a little too easy.

It's quiet.
Yeah, a little too quiet.

Look, there's raph.
Yeah, a littletoo Raph.
