Topic: Favorite Easter Eggs?

I couldnt find a topic about this, so I thought I'd start one.
To start it off, Totaka's Song is perhaps the most widely known Easter egg, as Kazumi Totaka puts it in almost every game he works on. He even has his own character in animal crossing, K.K. Slider! You can access his song in animal crossing by making a request for "K.K. Song".
What are your favorites?

White chocolate....... oh not that kind err not sure if this counts but the Sega Saturn you can find in Shenmue was pretty awesome.

I'm having a hard time remembering a lot right now. But I really enjoyed the Zelda: Skyward Sword theme played backwards. Very clever.

@HarmoKnight he's a No-Hoper. Cranky was right! :3

Super Mario RPG (which I finished not too long ago) had quite a few. Link & Samus were resting at various points in the game. The "8-bit" mario trick in Booster's Tower, as well as the Samus doll. The Final Fantasy inspired hidden boss, complete with FFIV boss battle theme & FF victory fanfare. The most perplexing, however, is in Toadstool's (Peach's) room, as when you check inbetween the fireplace & the chair, Toadstool will berate Mario for snooping around her room (if you search before she joins your party, her grandmother, being in the room, will urge Mario not to go over there, and give you an item to stay away, lol).

A cool one for me, however, is Link's grave in the original Final Fantasy.

TOASTY!

The scarab gun in Halo 2, no contest. I loved firing that thing and decimating everything with it.

What do you mean he is lost? DK has found the light with the sonic shoes

what game? The only toasty I know is Otenko from Boktai/Lunar Knights

I love all the Red vs Blue easter eggs in Halo 4.
I also like the Here Lies Link gravestone in Final Fantasy.
And not really an easter egg, but in Link's Awakening, the Mario brothers areas.
