Good Questions: Graduation, Roadkill & Eggs

MINNEAPOLIS (WCCO) – It's Friday, so that means WCCO's John Lauritsen is answering some of your Good Questions.

Darrin from Woodbury wants to know: Why do they play "Pomp and Circumstance" at graduations?

Graduates will no doubt be marching to "Pomp and Circumstance" this spring.

The song was composed by Edward Elgar. Also known as the "Graduation March," the song was first played at a graduation ceremony for Elgar himself in 1905.

It was so well-received it spread to other schools, and eventually to pretty much every graduation ceremony to date.

Several viewers have asked: Who takes care of the roadkill on Minnesota's roadways?

According to MnDOT, roadkill responsibility for removing that poor deer or raccoon falls to individual jurisdictions.

The state takes care of a state-owned roadway. The county takes care of county roadways. And each city is responsible for roadkill on city streets.

MnDOT said, for fear of not spreading disease, roadkill is typically moved to ditches so it can decompose.

Josie from Chaska wants to know: Why are some eggs brown and some white?

The answer is actually pretty simple. White-feathered chickens with white ear lobes lay white eggs. Red-feathered ones with red ear lobes lay brown eggs.

That doesn't apply to all breeds, but most.

Even though they look different, nutritionally there's no difference.
