He was a shlubby business man. He had no interesting visions, no pronounced attire. He was prone to thinking that his gimmicky ideas, dreamed up at the bar, were original and financially fruitful (he could make millions).

She was shlubby. She was disheveled in dress. She worked from home telemarketing or providing phone sex services. At night she goes to the bar and compliments shlubby men's ideas hoping to lasso them into bed. She is also intrigued by their conceptual money making ventures. She receives one check every month from the government and one additional check from a outside party- probably an ex-husband.
