Belly Laugh: Randy Houska's Joke About Chelsea's Baby Bump Was Reliably Uproarious

The comical 'Teen Mom 2' grandpa is at it again

Randy Houska memorably joked that when he learned his daughter Chelsea was pregnant with kiddo #2 he thought his "head was going to explode" from happiness -- and added an accompanying photograph of an amplified version of his face (thanks to a Snapchat filter). Fast-forward to the final trimester, and the Teen Mom 2 Yoda-like grandparent is continuing with his priceless comments about the brand-new addition to the clan.

"Unfortunately, I look further along than @chelseahouska does plus she gets to lose her belly soon #babydeboer," the self-deprecating dentist captioned the photograph of the duo. Oh, Randy!

In addition, Aubree's mama -- who is due on Valentine's Day and will return to MTV with her cohorts on January 2 -- proudly flaunted her nearly full-term bump with her bestie Chelsey Grace.

"Ummmm how hot is @cgrace13 ?! Annnnnd how can this belly possibly get bigger," Mrs. DeBoer added about her "little Coley."

Be sure to stay with MTV News as Chelsea gears up to welcome her son -- and don't miss the premiere of Teen Mom 2 on Monday, January 2 at 9/8c (get a glimpse of what's to come in the trailer below).
