Funny how the biggest star is named "Big Dog". I recognized all the names until it got past Betelgeuse.
What I like too are the examples that show distance... i.e. the ones that are like "If the sun is as big as a basketball, then earth is the size of a ball bearing that's 100 yards away, Jupiter is the size of a ping pong ball that's 300 yards away, etc." or something along those lines. Gives a cool perspective of how big the orbit is.
BTW, a red giant is the size of Jupiter's orbit around the sun.
