WWII vet asks for 100 birthday cards for his 100th birthday. Then something amazing happens.

Joe Cuba, a World War II veteran living in a Texas senior living center, will celebrate his 100th birthday on Saturday.

His only birthday wish was to receive 100 birthday cards — but he got a lot more than he bargained for.

What happened?

Cuba, a resident of Brookdale Midwestern, posed for a photo holding up a sign with his request. The photo was shared on social media and went viral.

The sign read, "I'm a WWII veteran who will be turning 100 on March 2, 2019. I would like to receive 100 birthday cards."

According to the Houston Chronicle, he received at least 10,000 birthday cards so far, from all across the globe. In addition to cards, the WWII vet also received blankets, coffee mugs, and more.

Cuba told the outlet, "Well, I thank every one of them. They did give and that's what counts."

Since launching the mini-campaign on Facebook, Brookdale Midwestern has kept social media users abreast of new developments.

A Feb. 22 post revealed that Cuba was inundated with gifts, cards, and well wishes.

On Tuesday, the senior living center posted another update revealing that the gifts have continued coming.

According to KFDX, Cuba grew up in nearby Megargel, Texas, with his 11 siblings. He married in 1943 and later enlisted in the Army Air Corps. He returned home to Texoma.

Cuba's advice for life is to seize the moment.

"Just keep on trucking. When you like to do something, do it," Cuba said. "If you don't, don't. But I'll say if you're interested in something, and have a chance to presume then life will get a hold of it and stay with it. Stay with something and you'll get ahead. You'll be okay."

If you want to mail Cuba your own birthday wishes, you can send them to Joe Cuba, 918 Midwestern Parkway, Wichita Falls, Texas, 76302.
