Hmm, what about implenting 'Potatoe' as a dialog option in a very important conversation in the game?

'Hurry, Dragon Slayer, an army is attacking our beloved village while a mighty dragon is about to devour your family! Which will you save?'

1. Lead me to your village, quick! We got no time to lose!
2. I must save my family, you'll have to deal with those villains yourselves!
3. Potatoe!

I'd go for the 'Potatoe!' option, just to see the outcome :p
