That would be the Groofus(?) puppet to Polo, who is torturing Framkin in Smile Time.
“He is very fortunate to have such a woman looking after his weapon.”
WOW… this is still going… (I know it’s been ressurected a few times - but wow)
and annoyingly I STILL DON’T KNOW…!!! GRR ARGH!
That would be the Groosalug (sp?) to Fred after she reminds Gunn to take his machete in Double or Nothing

Riley - to Spike in season 6 - “As You Were”???

1 Spike to Buffy in Fool for Love
2 The Master to the brothers of Aurelius in Never Kill a Boy on the First Date
3 Buffy to the Potentials in Showtime
I have to say, this game has sharpened my skills. Now when I watch the DVDs or read the TV Guide, I make special effort to remember episode names. Not that it always helps.

“From beneath you, it devours”
D’Hoffryn to Buffy, Xander and Anya in Selfless.
