When Larry runs into the homeless man he is referred to as 'the duck l'orange guy'. This is a reference to the dinner party in Aamco episode later in season 1. So originally the episodes were intended to be in a different order.
Despite the bad news outside the jeweler's, Richard Lewis is up-beat. Larry calls him "Norman Vincent Lewis", this is a play on the name of Norman Vincent Peale, a minister and author who popularized the concept of 'positive thinking'.
