Almost, BtP, but not quite. That semicolon should be a colon to indicate you are subsequently providing a list. The semicolon should be used for lists containing internal punctuation, for closely related independent clauses where a conjunction is not used, and for independent clauses linked with an adverb or transitional phrase. "Betty White and Nancy Pelosi" is not an independent clause, and the list does not contain internal punctuation.
Dalar's first example does have three options, since it is read that he saw four people (two strippers + Betty White + Nancy Pelosi). It would be less ambiguous to alter the the order in this way: "Last night I saw Betty White, Nancy Pelosi, and two strippers."
