[PCIntern]

Makes ridiculous statements which he has to retract, has outbursts, has affairs and leaves his wives precipitously without regard for immediate or long-term consequences, buy jewelry for his 'glam' wife which he cannot afford, is grossly overweight, implying constant eating or drinking sugary or alcoholic beverages.

Yes, a real winner...if you're a counselor/psychiatrist looking for a Therapy Candidate.
