Okay, so yknow how there are cute ways of asking someone to Prom?

Well since he's nerdy and a bIG fan of Pokémon, I was thinking about making a Pokémon card (it would look like the back, with the Pokéball too) and have it say either
-"PokéProm?"
-"Prom?"
Or
-"Ale , Prom?"

And I'd put at the bottom in black pen "Will you to the Prom with me? -Ruthie"

Or I wouldn't do the card and I'd just shuttle him off to the side towards the end of class, and ask him face-to-face.

Which should I do?
