Microsoft Corp., Charlie
In what appears to be an ad variation on the campy 1980s program "Three's Company," two women and a guy are sitting around a kitchen table laughing, when someone rings the doorbell.
Looking through the door's peephole, the woman recognizes the muscleman calling as Charlie (who kisses his bicep as he poses for the peephole), seemingly her boyfriend.
The guy already there says, "Oh no, do something" -- perhaps suggesting he might be thought of as her lover. He uses the software somehow to "paint" himself to look like a woman instantaneously. As Charlie walks in, he sees the "woman" and flirts with a seductive "Hi," as the guy (now wearing a wig, dress and makeup) flirts back.
The ad for Office XP's Task Panes function carries the tagline: "Experience the joy of doing things the new way."
