According to Sam, a couple of them should. To be specific:
Now do you see the resemblance? Perhaps this will help.
Yeah, I'm not sure I really see it either. But every time Sam plays with his Veggie Tale nativity set, he calls Larry the Cucumber (on left) "Dad" and Pa Grap (on right) "Mom." I realize that pregnancy hormones have changed my look over the past several months, but I was hoping the new handlebar mustache and purple nose weren't quite so noticable.
In any case, at least Sam treats his parents-in-effigy kindly. He finds them cozy beds in drawers and boxes, and often requests that Coach or I "talk to Sam" through our respective vegetable character. Sadly, Sam doesn't take the news that "it's time for bed" any better from a vegetable than a real live parent.
