Best playstation game secret?

What's the best playstation secret/ easter egg you've ever seen? Please share, maybe if there's a video share that? :)

Not the best, but my favorite is the "Large Sword of Moonlight" in Demon's Souls. It's the Starting weapon of the old game King's Field 2. ^^ FROM SOFTWARE is a good company.The best I think was in MMX8 the Cutman Boss battle. :D

The numerous references to Diablo in Borderlands, although they're probably not the best, and not Playstation exclusive.

Playing Fallout New Vegas with the Wild Wasteland trait.
I found uncle Owen's and aunt Beru's carbonized bodies.

Keep it up :)

I only payed attention to easter eggs in OoT..

I think my favorite easter egg is the fish easter egg in Boarderlands, although its not a psp exclusive, but from sony, I think the best easter egg was Metal Gear Solid
- Psycho Mantis Reads Your Mind :) that was cleverly done and well implemented

I like the golden chicken in gears

Fallout new vegas: found Indiana Jones's dead body in a refrigerator (location is somewhere near the first starting town) had a nice chuckle to that :p
