The blonde lady with the bountiful butt is Nicole “Coco” Austin, wife of rapper/actor Ice-T.
The guy with the fancy uniform is Major Archibald Willingham Butt (1865 – 1912). Major Butt fought in the Spanish-American War and was a military aide to US presidents Theodore Roosevelt and William Howard Taft. He died aboard the RMS Titanic when it sank after striking an iceberg.
Major Butt apparently had nothing to do with the buttset, but deserves to be
remembered here for having achieved success despite a dumb name. He was probably
the butt of many dumb jokes (like this one). There's a fountain named for him
near the White House, a Butt
Memorial Bridge in Georgia, and a plaque honoring him in the Washington
National Cathedral.
