Well, while promoting "Mr. Popper Penguins" Jim did mention he was up to "revisit some old characters" and he did mention "Dumb and Dumber" and "Bruce Almighty".
It really depends on a lot of factors but it seems to me like 20 years later he is actually open to do it.
Let us pray it will work:
"Oh my Boing! Enlighten Jim's hand, protected us from haters and stockarazzis and show us the path of pure Boing. Boing!" Lololololol
Sorry poeple, couldn't resist!
