For all of the non jews on here this is the description of the slang term Schmendrick (Yiddish) and I really feel it rings true to this Marty guy...
schmendrick definition
[ˈʃmɛndrɪk]
and shmendrick
n.
a stupid and ineffectual nobody. (Yiddish.) : Some schmendrick from downstairs asked if you could turn down your stereo.
Yeah his show... its sad im even wasting my time with this piece of filth...
More like a schmuck, or a putz.
