"He always said, ‘Get a catchphrase, you need a catchphrase.' I'm not kidding you," Stamos said during his TV Land Icon Awards acceptance speech. "The 'have mercy' thing came out of, 'Oh s**t, Garry told me I had to have a catchphrase."

Thanks for the news! I love when Jesse would say something like, "Just tell the story, huh?" :D :D :D

God bless you always!!! :) :) :)

P.S. I also loved watching him slide across the kitchen counter, especially after Danny waxed it that one time! He was like, "You waxed the counter?" and Danny said in return, "Yeah! And you just buffed it!" :D :D :D
