One of the running-things in "Doctor Who" is The Doctor (atleast before 'new' Who) during tense times would go "Want a jelly baby?" and offer them to people. Well I was wondering if they were a UK!only sweet, so I searched them. On the Wikipedia article it mentioned "Screaming Jelly Babies", and I just COULDN'T resist finding-out more :D
I've never heard the term 'jelly baby' (and didn't pay much attention to the candy isles in the UK beyond Cadbury's), but we do have gummy bears in the US and our German teacher use to give us Gummibärchen (the original German version).
Edit: I found this image while checking my spelling for 'Gummibärchen'.
