Here's my drift on our favorite goof-off, Carl. While still a lad in high school, he attended the local house of learning so his family can keep on eye on him (possibly one or both of his parents were still alive) because he was such a trouble-maker. Although his practical joking did not endear him to the teachers, he was rather popular among his fellow students, including the girls who got a kick out of him. However, they didn't take him seriously, so he never managed to have a sweetheart, something which always caused him angst.
It was decided by either his parents or by Grandmamamama (if his parents were by now deceased) that he would go to college. Edward went (Harvard). Judith went to a "ladies' college", aka a "seminary", aka a "finishing school". Quentin went, but was expelled after only one year. Alas, for Carl, the same would befall him. He just couldn't keep from playing those practical jokes. Glue on the professor's chair. Bustle raids on the near-by ladies' college. Drawing "indecent" pictures on the chalk boards. Sneaking the college mascot (a billy-goat) into the Dean's office where it promptly chewed up a stack of papers regarding donations from alumni. Enough was enough of the rabble-rouser, and all the Collins' money in the world couldn't convince the board to keep him. Frustrated Grandmamamama threatened to send him off to a college in Germany where the Kaiser would put him on the straight-and-narrow, but the prankster, in tears of fear, pleaded not to be shipped away. He spent his time just hanging around Collinwood and Collinsport, using the allowance given to him to entertain friends (who only liked him for his money), but occasionally going off to Boston or New York to see what kinda trouble he could get in there.
