A Joker
We may never know exactly what Kathryn saw in Chris, her fiancé. He was undoubtedly a joker; he loved to make others laugh, and perhaps even more so, he loved to make himself laugh.
His favorite pastime was to pull pranks on his friends, family members, and even his coworkers. The jokes he told were always hilarious to some people, but some others found them a little less so.
