WEST HOLLYWOOD - During his marriage to Heidi Montag, Spencer Pratt was always looking for ways and means to make a dollar.

A close, unnamed source revealed that when Spencer saw his wife Heidi's boobs, he just did not see knockers, he saw hooters filled, not with silicon, saline, or saltines, but tits stuffed with dollar bills...$100 bills.

Pratt wanted Heidi to put out a nude calendar, a nude cookbook, and even a nude Heidi Montag Action Figure Doll that when her string was pulled would remark, "Hi, my name is Heidi, but you can call me Heidi Ho."

Spencer even tried to get his wife to be one of the contestants on the upcoming season of Dancing With The Stars. But the shows producers felt that with her enormously huge breasts the possibility of having a 'wardrobe malfunction' during one of her dances was a distinct possibility.

Even Playboy mogul Hugh Hefner had been approached by Pratt about having Heidi appear in a spread titled, "The Women of Plastic."

Hef reportedly liked the idea but he did not like the fact that Pratt's and his idea of Montag's fee were not even close.

When Pratt brought up the fact that there was a sex tape that he had personally taken of Heidi and Playboy Playmate Karissa Shannon, the 97-year-old Hefner perked up.

He told Pratt that he would like to see it and that if it had the right amount of 'gazonga shots,' 'keister shots,' and 'beaver shots' that he may be interested.

SIDENOTE: Spencer Pratt has always been one who certainly covers every base. He has put a two minute vignette on the Internet and so far he has received about 70 offers to buy, produce, and distribute the sexy romp between Heidi and Karissa.
