Crack Mansion

The Crack Mansion is a very posh crack. Its patrons are treated very well, with butlers offering to pre-warm their crack pipes. It was visited by the crack addict after he received his $300 tax rebate.

Trivia

 * The Crack Mansion is ironic because crack houses are often in run-down and abandoned s, in contrast to a posh mansion.
 * A "Crack Mansion" may be understood as a higher class of crack establishment than a crack 'house', the same way as a mansion is typically understood as a higher class of dwelling than a [family] house. The joke is, of course, that 'crack house' is not a class of crack establishment (where all classes are prefaced with 'crack' [+class name]), but rather a generic name for any location where crack is routinely used.
 * This is a similar form of joke to the Admiral Crunch and Archduke Chocula breakfast cereals, where both mascots have gotten a promotion since the 21st century, except that both mascot's names are meant to be integral wholes, rather than a rank-name combination.
