Starting Over

I've been trying to translate the russian signs from www.sorryeverybody.com. The one in gallery 32, which says:

я из америки
я не понимаю
простите

means:

I am from America
I do not understand
Sorry

The one in gallery 35 says:

молодце американци
не плюй в колодец
случится воды напиться

I don't quite understand this one though. The first line says, 'young americans.' I think the second line says, 'do not spit into the well,' but the third line isn't making sense.

I changed my settings to where I can type things in russian now. I just need to learn the keyboard layout for it. I'm starting to get the hang of it.
