USA - 80 years old and not a bit tired: Bill Webb, affectionately known as Papaw, laughed himself silly when he saw what his family had come up with for his milestone birthday. It was a trip down memory lane that not only amused the birthday boy.

The imaginative fun can be seen in a viral TikTok video: In it, his granddaughter Kenzie Greene (21) and other young family members slip into the 80-year-old's old clothes that he has worn over the past decades.

Whether football kit, wedding suit or even his workman's outfit: the young people show Grandpa everything and show him the matching photos of him wearing the clothes himself.

Greene, who has attracted an audience of millions since January 19 with the curious video, spoke to Newsweek this week about her successful feel-good clip.

"He was thrilled!" she said of her grandfather's reaction - and immediately revealed which of the many eras he liked best.

College was the best time of his life , her grandfather said, according to Greene. Incidentally, she herself is currently studying at the University of Tennessee in Knoxville.

However, the idea for the "fashion show" did not come from the grandchildren, but from Webb's three daughters.

"My mother Stacy helped work out the plan and we made sure we filmed it to capture the moment," explained the 21-year-old student.

Her grandad is definitely the best! "He and Nana always come to every grandchild, whether it's a sporting event, a school event, a birthday or a holiday. We just wanted him to feel celebrated and loved," Greene gushed to the US magazine.

No wonder everyone went all out to honor their grandpa under these circumstances!
