Greg describes he gives his great nephews anything they want for Christmas, but sometimes ends up with the wrong gift. When Greg was seven, Greg wanted a Barbie Dream House so he could use it as a fort for his toy soldiers. He asked his parents for one and Susan thought it was a good idea,but Frank didn't like that idea as he thought it was too inappropriate for boys. Susan and Frank started fighting, but Frank won. Greg knew he had no chance to get it but ask Charlie, so he asked him to give it. But, Charlie, instead of giving him the Dream House, he went straight to the store and got the first thing that said 'Barbie' on it, which was a Beach Fun Barbie. Greg still played with the doll sometimes, but ended up in the hospital after the doll's shoe somehow got inside his nose. In the first book Greg asked him for Twisted Wizard but he gave him a photo of him which was about the same size as Twisted Wizard's game box. In The Last Straw, he gave Greg a thing called Laundry Hoop which was a Laundry Bag in the shape of hoop. Greg told him he doesn't do his own laundry and don't need it and said that he should give Greg cash instead. Susan thought it was a great idea for Greg to do his laundry in a 'fun' way. This made Greg get a new chore to do his laundry. Greg mentions that he has a lot of cash and spends most of his day sitting on his recliner. When Greg was little, he gave Greg a nickname "Red" and used to call it all the times, this was because Greg used to have red pajamas, though, soon Greg starting getting serious about it and told his mom how he felt. Susan bought Greg a pair of blue pajamas and Greg went to Charlie looking at him in a way that he has lost, but Charlie started calling him "Blue".
