She happened across thunderdome!
Mike, can't we just get beyond thunderdome?

Looks like that seed planted back in MST season 6 paid off finally. Anyone else catch that? Sorry if this is a repost... can't think of the exact episode off the top of my head, but there was a big bit in a season 6 episode--"We've tied up Mike and stuffed his mouth with oily rags so we can bring you a snappy comeback... if you live long enough, eventually someone will mention 'Thunderdome' in your presence." (And so on.)

It was Laserblast, the false alarm last episode.
