If you don't have one then you obviously need one. If you do have one then you already know the joys so you need another.
-Fun to shoot
-They are really cheap to buy
-Ammo is inexpensive compared to other center fire rifles.
-You can play Enemy at the Gates on DVD while cleaning it.
And most importantly.....
If you don't get one a puppy will die and it will get out that you touch yourself at night while watching reruns of Gilligans Island. And NOT
because of Ginger or Mary Anne
I'll be looking forward to the pics of your new rifle...
