@Riot - Do you guys still add in easter eggs?

It's been a while and I've not heard of any new easter eggs or story quests (like Battle for the Frejlord), and I was wondering if they're still being added. It would be a shame if you guys have stopped making them, because they're pretty entertaining.

On that note, can we potentially get little "buffs" for instances where the hidden ones show up? Like "Sun Protection" if your champ wears shades against a Leona, "Cougar" when Nidalee is near a lower leveled champ, or "Plants vs. Zombies" if you play Zyra/Maokai against Sion/Kathus?
