As LT said earlier, the past tense of "PAY" is "PAID".
The past participle form, "PAYED", is incorrect.
Your title should read "My friend is an idiot." or "My friends are idiots."
Acutually, I think he intended to have the title be "My friend's an idiot." He's only missing an apostrophe, which happened to inappropriatley show up at the end of the title.
