The Rock and others talk about his guest appearance on Star Trek: Voyager.
He played (what else?) a super-strong alien.
Both Smackdown! and Star Trek: Voyager were on UPN at the time; hence the cross-promotion; in case you were wondering why this was happening…
You can read more about The Rock’s appearance on the show in his Memory Alpha Star Trek Wiki article here.
I hope R.D inducts the episode proper one day.
