The more I read about Marty, the more I'm convinced he would benefit from some quality psychiatric help.
You're not kidding! Marty has a "Narcissistic Personality Disorder" (NPD):
"To meet the diagnosis of a personality disorder, the patient's problematic behaviors must appear in two or more of the following areas:
perception and interpretation of the self and other people
intensity and duration of feelings and their appropriateness to situations.."
..."He or she has a grandiose sense of self-importance (exaggerates accomplishments and demands to be considered superior without real evidence of achievement).
He or she lives in a dream world of exceptional success, power, beauty, genius, or "perfect" love.
He or she thinks of him- or herself as "special" or privileged, and that he or she can only be understood by other special or high-status people.
He or she demands excessive amounts of praise or admiration from others.
He or she feels entitled to automatic deference, compliance , or favorable treatment from others.
He or she is exploitative towards others and takes advantage of them.
He or she lacks empathy and does not recognize or identify with others' feelings.
He or she is frequently envious of others or thinks that they are envious of him or her.
He or she "has an attitude" or frequently acts in haughty or arrogant ways."
