Ratteners
As disgusting as this job may seem, we still think it’s not the worse job on the list. Back in the day, professional Ratteners were hired to catch rats around urban cities. However, the rats weren’t caught for sanitary purposes, as you might’ve thought (well, not solely) – they were caught for entertainment purposes. Local pubs would pay Ratteners to bring them rats, for their guests’ entertainment.
We don’t see what can be so entertaining about rats, but we’re not here to judge. It was only later that authorities realized this was a good practice to help keep the cities sanitized and clean from rats, and the responsibilities of Ratteners were extended.
