Apparently the whole "extended breastfeeding" thing has been around for years in Little Britain, as this clip from a BBC documentary explains:
Little Britain, Series 2: "Bitty" [google video]
Hmm, I assumed that it was a documentary; everyone had British accents. Little Britain homepage [bbc.co.uk via dt reader carlajane]
ah yes, little britain. that show is damn funny. the only one worth watching on bbc america currently.
"Do you take this woman to be your lawfully wedded wife?"
...
"Bitty."
even more funny/disturbing are some of the posts on craigslist by adults looking to suckle the teats of a lactating virtual stranger
[i believe that's a real stranger... -ed.]
