Tyler's role in The Last Straw
Greg also tagged along, but he instantly regretted going when he saw the kindergarten-aged kids there. At one point, he told them that they should crash Holly Hills' party, but they were interested in kids shows like Sesame Street and little kid games like Blind Man's Bluff. At one point, Greg decided to leave because the kids were playing "Who licked me?" and he didn't want to get involved. However, he left his sleeping bag upstairs and couldn't sleep all night due to the sliding glass door being open. He got sick afterwards and was unable to go to the father-son campout to make a good impression on Frank in order to avoid going to Spag Union.
