The Good Framer

Recently, I bought a painting and as I was paying for it, the clerk asked if I would like it framed.
"Who's going to frame it? I asked.
"I am," she replied.
"Are you any good?"
"I'm fabulous," she answered. "There is only one person better than me, and he taught me how, but he's retired now."
"Well," I quipped, "If you're that good, you must be frameous!"
