The correct spelling of her last name is "Chappel" with two Ps, as seen in both "Take My Life, Please" (on her flyers) and in "Life Could Be a Dream" (on her letter). Her birthday is not August 3; Lowell is just a doofus. She says in "Four Dates That Will Live in Infamy" that she is a Libra, which makes more sense in the timeline for the episode "It's not the Thought, It's the Gift."
