Women who have breastfed in Australia, please take heed: your breast pump may have been cleaned by a 14-year-old Thor. That is to say, Chris Hemsworth revealed on Wednesday’s episode of The Tonight Show that cleaning dried milk out of rented breast pumps with a toothbrush was in fact a real job he had. The actor joined Kumail Nanjiani and Jimmy Fallon for a round of “True Confessions,†which is a little like a shorter version of Would I Lie to You? We also learn a very dark secret about Nanjiani’s childhood in which he was an attempted murderer, but don’t worry, it’s very funny.
