From Left to Right: Bart's boss, Harlan Gibbons, age 59. Harlan's a former middle-weight 1981 boxing champ from the UK. He retired and became businessman and worked his way up to become the Chief operating officer of the Springfield branch of the XL corporation. Harlan's a hard-ass boss whose net worth is close to half a billion dollars. A widow, he was left taking care of his adopted, Japanese son, Kyle, far right for the past decade. Harlan has also taken a liking to Bart's attitude, so much so, he essentially made Bart give up his morning show DJ job and he promoted him to assistant TV programming director, under his son Kyle.
In the middle, is Kyle's often drunk and skanky GF, Sheila. Seemingly always with a bottle of wine, she's the party girl who is riding off of Kyle's rich coattails. Shelia has known Kyle since they were sweethearts in private school and after all the partying, she became an alcoholic.
And on the far right, Kyle Gibbons, Harlan's son. Kyle is a very ambitious and very stern 21yr old who is the director of programming for the Television side of KBXL. He is in charge of dealing with advertisers and scheduling programming and is often belittling Bart with demeaning tasks like getting the coffee and washing his dad's car.
