- One baby doll
- One (or two) pairs of small skivvies (a.k.a. underpants)
- One small juice box with straw
- One long ribbon
- a little time alone in your bedroom
Then, go into living room, find your father, say, "Look, Daddy." Put the doll's butt up by Daddy's face, and squeeze the juice box. Listen to gurgle of juicy air, and delight at Daddy's surprise.
Voila! The farting baby doll.
P.S. I would SO love to include a photo with this post, but my camera is still MIA.
