During that episode of 'The Middleman' dealing with "The Vampire Puppet Lamentations", Wendy Watson was looking forward to going all Buffy on the vampire's ass - before she found out that it was a puppet.
This was a reference to Buffy Summers, formerly of Sunnydale, California, who was chosen to be a Slayer in the fight against vampires and demons. Buffy had her own show, subltly called 'Buffy The Vampire Slayer', and has since gone on to become one of the darlings of the Multiverse. She began "life" in a movie starring Kristy Swanson, appears in several tie-in novels, had a proposed cartoon series pilot produced, and is currently starring in a comic book series, which has gone mega-hot recently!
Still, we're just concerned with the TV Universe, which Buffy should be sharing with Dub-Dub (who, by the way, began "life" in the Comic Book Universe with her Bossman).
Have no fear, Toob Believers! At Middle HQ, Ida would have had a complete dossier on Buffy Summers; in fact, she'd have files on all of the Slayers and their Watchers - just in case their paths crossed one day. The Middleman would have insisted that Wendy study these files in order to be prepared for such a possibility.
And thus, no Zonk.
