Or at least things I sometimes do when I'm bored...
  1. Look at people's shoes and then guess what they look like before you look up.

    You would be surprised how wrong you can be when you judge a person by his feet.
  2. See how far you can lean on the person next to you before they notice.

    I'm not saying to grope them or anything, just a subtle lean.
  3. Choose one person you want to be near and one person to avoid before getting on
    Giphy
    Make it your mission throughout your journey to keep it that way!
  4. Play "the floor is lava."

    Pro: this is also a great leg exercise! #legday
  5. Time the normal length between stops and try to find songs on your phone of exactly that length
    Giphy
    Next time you take this journey, you'll have an awesome playlist! Go you!
  6. Wink at people until someone winks back. See how many it takes!

    If the return winker seems creepy, this might be a good time to play the"avoid one person" game described above
