That is one way to put it, this guy is gonna get screwed up one way or another

Actually, a multitude of studies have shown that sleep deprivation very rarely causes any long-term, or short-term issues. The only recorded instances of people "changing" after a very long session of no sleep was when they abused stimulants such as amphetamines; psychosis, depression and so forth.

Sleep deprivation is dangerous if you have long-term insomnia, but if you are just doing it on purpose once in a while, it's extremely unlikely that you suffer any grave consequences.

Oh, well I meant like doing something like passing out at the wheel or something like that.

I absolutely agree. Though, I have enough common sense to not operate any heavy machinery, or go out and 'bout driving when this tired. Right now, I feel pretty good actually, which is odd since about 30 minutes ago I felt like dying. Might be the absurd amounts of caffeine I'm taking though...
