i meant the least stupid way to implement some thing like it on an easter egg scale. i do agree that new ideas are prefarable.
On a thread about easter eggs (this one What about EASTER EGGS?) I made this comment:
Two npc’s are talking to each other
"Bah! I hate all of these damn rats!"
“Consider yourself lucky, I’ve heard that in some places there are rats the sizes of dogs that require professional mercenaries to kill”
"That’s just fantasy rumors…"
Obvious reference to TES fighters guild quests 
Or an NPC talking to the player
"I would like you to kill 10 cows and then report back to me"
“Really?”
"Of course not, what use are the cows to me dead?"
MMO reference
Dialogue easter eggs are probably the most story-friendly and funny to me.
