It was caused by an app he just downloaded..
It's nothing new. It's always been there.
I saw it on day 1 when I installed iPint. iPint has since been removed from the US AppStore. I don't know why.
'Lead' can read like two totally different words, what can 'pint' refer to other than a weight?

Maybe to release with a more compatible name as most Americans misread Pint as much as they misread Lead. Kind of like Lead Zeppelin had to change their name.
