40. Ellen DeGeneres

Location: Mama’s and Papa’s Pizzeria

Initial cost: Unknown

Amount added: $1,000*

Notorious for her generosity, Ellen DeGeneres, during the 2014 Oscars, made headlines by ordering pizzas for the stars from Big Mama’s & Papa’s Pizzeria. Delivery man Edgar Martirosyan, who brought the pizzas, however, left without a tip.

Discovering Edgar Martirosyan wasn’t tipped, Ellen DeGeneres rectified this by giving him $1,000 on her show. This act of kindness not only rewarded Edgar but also unexpectedly boosted his employer, Big Mama’s & Papa’s Pizzeria’s, sales significantly after the Oscars and Ellen’s broadcast.
