Just to emphasise this properly, Dwayne Johnson hasn't had sweets/'candy' since before Taylor Swift was born.
The Rock was on The Tonight Show with Jimmy Fallon last night to promote 'Central Intelligence' when a major revelation was dropped. Turns out Johnson hasn't eaten sweets since 1989 because they're just not his thing.
So of course, all Fallon could do with this information was bring out a plethora of sweets to tempt him (including a barely SFW giant gummy worm) before they both settled on Pop Rox.
