What lies in bed, and stands in bed, first white then red. The plumber it gets, the better the old woman likes it?
Common Wrong Answers
“Egg”
An egg lies in a nest (not a bed) and can be white or brown, but it doesn't turn red and is not related to plumbing.
“Tomato”
While tomatoes can be red and are grown in beds, they don't typically lie in a bed nor stand in the same way as a strawberry does, and the riddle's reference to plumbing is not applicable.
“Rose”
A rose lies in a bed (flower bed) and can be red, but it doesn't get 'plumbered' and doesn't fit the context of the old woman liking it.
