Little Johnny is riding with his Uncle Bob

Little Johnny is riding with his Uncle Bob in his new Mercedes.

Johnny points at the star emblem on the front and asks,

“Uncle Bob, what’s that star for?”

Uncle Bob grins and says,

“Oh, that’s my guide—it helps me stay on course.”

A few minutes later, Uncle Bob narrowly misses a cyclist, and Little Johnny laughs,

“Good thing it’s there! Without it, we might need more than just a map!”
