Waiter, There's a Baby in My Soup Rugrats : Season 1 Episode 3

Stu and Didi ended up taking Tommy to an important dinner at "Chez Ennui" with Mr. Mucklehoney (president of Mucklehoney Industries, a toy company), since Tiffany the babysitter (via telephone) and Grandpa have different plans (the babysitter's OTHER goldfish died and Grandpa was going bowling with a friend of his named Louise). Tommy, however, has plans of his own, and proceeds to get loose in the resturant kitchen, causing absolute chaos.
