The Chicago Cubs have a lot to be excited about. They're a much improved team in 2015, with a wealth of young, exciting players. Unfortunately, with youth comes occasional stupidity.

Cubs outfielder Junior Lake hit a 2-run homer in the 6th inning of Wednesday night's game against the Miami Marlins. While rounding 3rd base, he appeared to make a gesture in the direction of the Marlins dugout. He then had some words with the Marlins catcher as the benches cleared. What makes this even more of a punk move is that the Cubs were still down 6-2 after the home run.  The Cubs went on to lose to the Marlins, 7-3.

In his post-game press conference, Cubs manager Joe Maddon said, "We don't do that here". Hopefully it's a lesson learned for Lake and the young guys on the team. Act like you've been there before.
