WESTON, FL - From sealing leaky boats to patching holes in hoses, Flex Seal’s long line of adhesives and upbeat ads have made it one of the most popular home improvement products in the world.

But their latest product, Flex Deadlock, which boasts the ability to lock your grandpa or other undesirable relatives behind doors for hours, has quickly taken the internet by storm.

“Are you sick of grandpa calling your Hispanic friends ‘dirty Mexicans’? Worried that he’ll shoot your neighbor's dog if it runs in your yard while you’re at work?” Phil Swift shouted gleefully in Flex Seal’s latest commercial. “Then try Flex Deadlock! With Flex Deadlock, you can seal your grandpa in the closet for hours so you can host dinner parties, date nights, or even just enjoy some self pleasure without worrying your house is going to burn down.”

To prove the product’s durability, Swift then guided an elderly man into a closet, applied the quick-drying sealant to the edges of the door, and watched as the man aggressively tried to open the door from the inside. “It even works for your other family members!” Swift continued. “Need a break from your nightmarish children? Lock them in the closet with Flex Deadlock! Sick of your dog eating your shoes? Lock it in the closet with Flex Deadlock! Want to keep your husband and his boorish friends in the basement on book club night. Make sure they don’t escape with Flex Deadlock!”

Since Flex Deadlock’s release, the company’s stock has gone up 124% and prompted the creation of additional products aimed at keeping different family members where you want them like Flex Knit - a strong and sticky blanket that makes it nearly impossible for your grandma to get out of bed - and Flex Pants - a velcro-lined garment that will keep children in their seats until they finish dinner.

At press time, law enforcement agencies across the country have reported finding Flex Deadlock at dozens of kidnapping and homicide scenes.
