Greg's Grandpa

"Grandpa" is the lovable but clueless grandfather of Greg, Rodrick and Manny, the father of Frank Heffley, the father-in-law of Susan Heffley and husband or ex-husband of Nana Heffley, whom he either divorced or is a widower of. His first appearance was in Rodrick Rules, where he offered to let Greg and Rodrick stay at his boring retirement community, Leisure Towers; the experience was terrible for Greg. He is favor to Greg. He was seen again in Dog Days, where he finally confessed to Frank at brunch that he ran over his dog, Nutty, enraging Frank. In The Ugly Truth, he appears at his son Gary's wedding, and the family reunion and even babysits Rodrick and Greg as their Gramma was on a cruise. In Cabin Fever, he appears only in a photo, but he makes a younger appearance when his son, Frank told him about his bully, Billy Staples he came to Billy's house along with his wife, telling Mr. Staples about Billy's actions. In Hard Luck, Greg mentioned that Grandpa had a girlfriend, because at Leisure Towers, a lot of women lined up at Grandpa's door trying to win him over with casseroles and baked goods. He started dating a widow named Darlene. His real name is also unknown. Greg is his favorite.

Personality
Grandpa is strange, unpredictable, and quite ignorant at times. He sets his TV only on the CCTV channel, which he enjoys watching, infuriating Greg as he cannot watch any "real" television shows at his grandpa's retirement home. He makes a dish called watercress salad, which is an uncooked salad with vinegar and green beans. Greg and Rodrick thinks it is disgusting; their grandpa seems to not care. He loves to play a game called Gutbusters as well, and forces Greg and Rodrick to play; Greg always wins because his Grandpa thinks the nonsensical jokes are funny and he also beats Rodrick because he laughs on purpose because he keeps his mouth filled with milk when Greg's turn comes. In The Ugly Truth, he is shown to smoke when no one is looking. He might of been told on by Greg, as he has never been seen smoking since.

Physical Appearance
Grandpa is always shown with his spectacles,but he takes them of when sleeping and even wears dentures and is short and overweight and wears old fashioned clothes and he also is half bald with only some hair.
