I’m guessing a typical response would be somewhere in the middle of these:
“Dude, quit trying to scam me, I’ll never fall for that crap. Now let me get my money from Nigeria. Apparently I have an inheritance.”
“That would never happen, so I have no reason to assume it’s legit.”
“That sounds intriguing, but you know the saying, 'if it’s too good to be true, it probably is' ”.
“Sounds great, but I’m guessing it’s risky. Tell me more.”
“Tell me how, I want this free cash!”
