Sour Sour Jokers Yes I had these too circa 1993 I believe.
Our local newsagents had them in stock for ages, they were 5p and lethal!
We had bets to see who could fit the most in their mouth at any one time, I think the most was 3, for about 2 seconds.
You could get green, blue, yellow, red but I think they tasted the same!
Brilliant sweets!!!
