Trains travel from one town to another town all day, always on the same track, always going nonstop and at the same speed. The noon train took 80 minutes to complete the trip, but the 4 PM train took an hour and 20 minutes. Why?
I flop around on sticks and sometimes you cheer me as I do, I desperately need a white powder to do what needs to be done, and looking at me you might wonder why I look like I am about to go swimming. What am I?
