WASHINGTON—Busy dealing with important paperwork and other vice presidential duties in recent weeks, Dick Cheney was forced to put off until the last minute a cherished annual tradition: gift-shopping for his favorite holiday, 9/11.

"I looked at the calendar yesterday, and I couldn't believe my eyes—9/11 is almost here!" a rosy-cheeked Cheney said upon returning to the White House Sunday with two giant bags overflowing with gift-wrapped boxes and big red bows. "It's the most wonderful time of the year."

While Cheney is known by many to be cold and taciturn for the other 11 months of the year, those close to the vice president say there is something about the 9/11 season that puts a smile on his face and a spring in his step. Each Sept. 11 morning since 2001, Cheney has come to work donning a fireman costume and handed out small, thoughtful gifts to all White House staffers. In addition, at his home on 9/11 Eve, Cheney lays out large piles of presents for his children and grandchildren underneath the colorfully lit, six-foot-tall 9/11 towers that he sets up by the fireplace.

"I think I've outdone myself this year—I bought the president a box of cigars and a brand-new fountain pen, I got Condoleezza [Rice] a beautiful blue blazer, and for my wife [Lynne] I bought a diamond necklace, a new winter coat, and this neat little motorized airplane ornament to hang on the 9/11 towers," Cheney told reporters while perusing the windows of New York's famed Park Avenue shops. "And for [grandson] Samuel I bought about a million toys and games and 9/11 nutcrackers. I probably went a little bit overboard, but it's his first 9/11, and I want it to be as special as my first 9/11."
