most of them just like to entertain... and they start as kids, with their families and relatives... and then they move on to birthday parties and so on and they just go on
obviously, they do have a talent to actually entertain, whether is juggling, magic, improv comedy, singing, dancing... all of of them, some of them and more... so they can actually make a living out of it
they don't exactly chose the clown life, the clown life chose them... lmao
