Lucky number 13

This is post number 13. One of my favorite numbers, because when compounded to a single digit, (1+3) you get four which is the square of 2 (2^2 = 4). I do math like that in my head a lot. Especially when I drive, I call it "Marc-matics". Get it? My other favorite game to play when driving is called 'In My Pants'. It's awesome, you read billboards and add the phrase 'in my pants'. It gets pretty suggestive, which is the entire point.
The best car-game ever though is "Cows". My friend, Matt told me about it a couple years ago. It involves driving and having people scan the sides of the road and adjacent pastures/fields for cows. When cows are spotted on, for example, the right hand side of the car, the player on the right yells 'I got cows' and then the number. Passing on a cemetary on the right of the car will kill of of the right-side player's cows. While getting thoroughly trounced by yours truly, The White Leroy saw a Sinclair station and used the dinosaur on the sign to eat half my cows. Since then, pretty much anything goes as long at 1) it's funny/silly 2) it makes sense and 3) I still win.
