Just wondering. When I say it, all I can imagine is some weird grandmotherly figure handing out cookies or candy saying "Ahh.. Which was nice." or something similarly creepy.
Wasn't it Weebles Wobbles before, or something equally weird?
Unless you've seen several episodes of the show itself, you can't really explain the humour involved. It's strange that repetition of the punchlines make them funny to a degree - hard to explain.
I bookmarked when its said Weebles Wobble, so it will always be Weebles for me which is bad as I used to have nightmares as a kid about killer Weebles.... and the damn witch from Chorlton and the Wheelies (that witches voice still scares me s***less, seriously I can't manage to listen to more than about 10-15 seconds of it) ).
