I always liked the Mondale debate retort.
I will not make age an issue in this campaign. I will not exploit my opponents relative youth and inexperience.
Even Mondale burst out laughing at that line. Even though he didn’t mean to. I’ve always believed that line right there assured the American people that Reagan was still up to the challenge and helped him win in a landslide.
Yep, quick wit and good humor goes a long way. It also says you're "sharp".
