Flavor-licious

If I could figure out how to make a contest of this I would, but in short, what are peoples most flavor-ful cards (I mean overall flavor although if flavor text is what catches your eye go for it). That card that you look at it and you say "that isn't powerful, it isn't good but man it is just plain fun I have to build a deck around it".  Use any card from printed sets or even MSE sets.  If it is an MSE set please provide an image or text of the card (I don't know these sets that well).  Personally I'd try to keep form using Un-sets as well but I understand if not (I'm not selling either my Infernal Spawn of Evil or my Infernal Spawn of Infernal Spawn of Evil).

The first card I ran into like this was Goblin Grenade, although after Food Chain and Onslaught everything tribal just lost its flavor to me.

Ovinomancer, is the card that still appeals to me flavorwise the most.  I still have a working deck thanks to Commander & highlander formats, as well as the plethora of Skyshroud Ranger style cards, I still have a pauper version, the Explorations were just to expensive to keep).  My commander deck receives some groans when I play with it but no-one ever complains about the Sheep Wizard.
