Referring to the Seinfeld episode where George's wallet was so overstuffed with junk that it made him sit at a tilt with it in his back pocket; forcing him to even it out by stuffing his other back pocket with napkins. Eventually, the wallet exceeds maximum density and explodes on the street in a shower of cash and receipts.
Time for some life skills training ... According to Guyism.com, here are some things every guy should have in his wallet:
20 Dollars in Cash -- Almost all businesses take debit and credit cards now, but every once in a while you'll run into a situation where cash is needed. A quick 20 does the job in most situations.
The Business Card of a Lawyer -- Consider this a simple (and cheap) insurance policy for you when things get out of hand and jail is a distinct possibility.
Matches -- Either a pack of them or one or two strike anywhere matches will do. It's nice to know that you have the right answer when a woman asks if you have a light.
The Phone Number of a Good Friend -- Write it down and put it in your wallet in case you're drunk and passed out. You don't want the authorities calling your mom. You want them calling someone who can get you out of this mess.
