The certain Republican presidential nominee appeared in a phony campaign ad in which he promised to put an end to runaway government spending, claiming he had never sought money for his home state, Arizona.
"Controlling government spending isn't just about Republicans or Democrats," he said. "It's about being able to look your children in the eye. Or in my case, my children, grandchildren, great-grandchildren, great-great-grandchildren and great-great-great-grandchildren, the youngest of whom are nearing retirement."
"I have the courage, the wisdom, the experience and, most importantly, the oldness necessary," McCain said. "The oldness it takes to protect America, to honor her, love her and tell her about what cute things the cat did."
Later, during the program's "Weekend Update" segment, McCain urged Democrats not to rush to choose between Hillary Rodham Clinton and Barack Obama.
When McCain hosted "SNL" in 2002, he performed a medley of Barbra Streisand songs. In an interview earlier Saturday, Glamour magazine asked if he would be singing again.
"I think once is enough," McCain responded.
