I hate Chairface Chippendale

I'd imagine he started crime at a young age. Learning from other criminals at 8-10 years old, and maybe moving on to this first incident as a teenager.

However, the supposed lore from the animated series' writer's guide, and the offhand comment Chairface makes about his age, would imply he's in his early 20s, whichhh... would mean he wasn't even ALIVE in 1965 lmao.

But seeing as the animated series is quite different from the comics, from the characters to the time period (about 5-10 years ahead) I could see the writers making him younger in the animated series specifically. It's a bit of a stretch imo but plausible.

And, if that were the case here, Chairface would have to have been making a name for himself for at least 8 years prior, given that Brain Child had known of his notoriety as an infant.
