LIFE OF RILEY. BtVS Intertext/Allusion.

In "The 'I' in Team," Willow and Xander talk while waiting for the arrival of Buffy, now training with The Initiative.

WILLOW: Go? You can't go. Buffy hasn't gotten here yet.

XANDER: Let's face it, Will. She's over an hour late. She's probably out living the life of Riley. I don't think she's coming.

WILLOW: She is! (unconvincingly) She said she was looking forward to spending quality time with just us. (brightens) See? Here she comes.

WILLOW: (crestfallen) . . .with Riley . . . and some other guys.

Xander refers to The Life of Riley, a television series starring William Bendix that ran from 1953 to 1958 on NBC. The IMDB offers the following brief summary

Riley worked in an aircraft plant in California, but viewers usually saw him at home, cheerfully disrupting life with his malapropisms and ill timed intervention into minor problems. His stock answer to every turn of fate became a catch phrase: "What a revoltin' development this is!"
