I am writing an essay on the impact Jack Dempsey and Babe Ruth had on America during the 1920s, and I was wondering if anyone could help me think of an interesting "attention grabbing" topic sentence such as a quote, question, or fact to start out with?

I was thinking maybe something that had to do with the "Golden Age of Sports" but I can't think of an interesting sentence...

All input is appreciated!
Thanks for the help!
