Venture Brothers cocktail: Sam in a Sweater?

In the episode, "Now Museum, Now You Don't", Rusty Venture orders a drink called "sam and a sweater" or "sam in a sweater" or "salmon the sweater". i have researched a bit online and have only come up with the following recipe:

"...Then you could start making up your own drinks like telling the bartender to make you a 'Sam in a Sweater'.

Bartender: "Ummm, WTF is that?"

"Well, you take 2 parts vodka, mix in some triple-sec, diet Cherry Dr. Pepper and a touch of cream and blend it with ice. Teeny umbrella garnish is optional. Do you have any curly/ bendy straws at least?"

[the idea of screwing with a bartender and ordering a drink that you made up on the spot is borrowed from a novel]"

But which novel?? Thanks to MicroBob on Vegas Drinking Prop Bet for the only reference to this drink that i could find...on YAHOO, no less!! Suck it, Googler purists...

In any case, i have found a few sweater-based cocktail recipes, but none of them seem to have anything in common. AlSto assumed, based on Dr. Venture's rather disgusting drink preferences, that this one would be no exception.

ERIN'S SWEATER is a 3-to-2 mix of Blue Curacao and chocolate liqueur, shaken and served over ice cubes in a champagne saucer!!!??? Thanks to drinkswap.com for this one. There is also the YELLOW SWEATER (with short sleeves) as given by barmeister.com: 1 oz. vodka, 3/4 oz. creme de banana, and 1/2 oz lime juice. Mix and strain.

With ice, i presume...???
