It was a comedy from probably the 1990s. It was two kids (maybe twins). I want to say they had blonde hair but can’t remember 100%. They were kind of bad but not extremely bad. They kept eating pizza everywhere they went and eventually got adopted by a rich family but the rich family gave them up because they ate too much pizza and threw up all over their white couch. I remember an alcoholic guy also adopted them and feed them only frozen/cold pizza.
