How am I supposed to discipline these children?

--

Bella wanted spaghetti for lunch on Sunday, so I obliged and made spaghetti! They decided it was way more fun to throw the noodles on the floor rather than eat them!!! I told them no and even said I'd put them in the corner if they did it until they started giggling - then I start laughing at them and it's just down hill from there! So you tell me how am I supposed to discipline these children?

On a side note - they did help me pick up each and every noodle they threw on the floor - actually, they picked them all up and handed them to me! So no harm done, right??
