Do Tori Spelling and Dean McDermott have an aspiring comedian on their hands?

At the ripe age of 3, their son Liam has launched his own Twitter account, LiamsWorld, where, with the help of his famous mom, he updates his 14,000-plus followers to his best one-liners.

"The response was not what I expected. It was insane," Spelling, 37, tells PEOPLE, adding that the toddler got more than 10,000 followers in just six hours after launching the page earlier this week.

Some one-liners that have had his parents and fans laughing: "Mama the moon ate the sun and made it dark. Will he burp him up tomorrow so it'll be a nice day?" And, "I love making jello castles. Jello wiggles and parties in my tummy."

That humor, Spelling says, has "really lifted" Dean's spirits while he's been recovering from a motorcycle accident.

"Once Dean came home from the hospital, Liam told Dean, 'You have to stay in bed. Doctor said you're sick. You have a boo boo,' " she recalls. "Dean is slowly recovering. He has a long road ahead and is still in a lot of pain. He's just taking it day by day, and the kids and I are good nurses!"
