Hugh Laurie as Dr. Gregory House - The brilliant if caustic doctor whose behavior may be off-putting to his staff and patients but the hospital would not be the same without him. Avatar courtesy of Walford Galleries' section for Hugh Laurie, as part of Hugh Laurie - Devoted to Hugh

Robert Stack as Eliot Ness - Before he was a mystery man, he was the original Untouchable Eliot Ness.

Robert Stack and Sailor Pluto - The Unsolved Mysteries host and the mysterious Sailor Pluto: quite a mysterious pair, ne? The latter half of the avatar inspired the Sailor Pluto main page layout in early January 2004.

U2 Meets Sailormoon

During their Zoo TV tour in the early 90s, U2's fans literally got into the picture behind their favorite group. Actually, U2 is in Tokyo, Japan (circa 1993), standing in front of two Japanese posters, one of them being the Sailormoon R Movie. At left, Sailor Mercury, Chibi-Usa, and Luna-P can be seen in the upper right corner. At right, more of the poster is shown enough to include Sailors Venus and Moon, and (slightly cutoff at the top center) Tuxedo Kamen and Fiore in the background.

I don't recall where exactly I got the picture at the left but for the one at right, I scanned it from the cd booklet of U2's "The Best of 1990-2000 & B-Sides".
