 In the scene where Danny and Rusty reminisce about their first  respective encounters with Reuben, they list the casinos on the  Vegas strips where Reuben taught them to gamble and, presumably, how  to perform their first cons. These casinos are the same casinos that  are robbed in the original _Oceans Eleven (1960)_ (qv): The Sands,  Desert Inn, Flamingo, Riviera and Sahara.
