Kids in the 1980s
Make modern children feel hard done by in telling them that curly wurlys used to be so big you could climb up them like a ladder and wagon wheels where so big you could use them on your bmx if you got a flat.

This is true
Wagon Wheels were about a yard across. and as for Cadbury Creme Eggs...

Sad as it it
but I have 7 Cadbury's Creme Eggs in the fridge from 2004-2010. They all weigh exactly the same. Originally I was trying to prove that they get smaller every year but they haven't for the last 7 years :(

I once saw a youtube clip
of a bloke comparing them. This may be older than 7 years though.

Edit:
This is it www.youtube.com/watch?v=_FiA57ir5QM. Quality is a bit dire though.
