Dads accumulate a lot of pens that have dried up.
* Use an empty pen as a clever way to hide some travel cash. Just roll up the bill tightly and slip it down the barrel.
* Remove the ink cartridge and use them as flower stems for cut flowers. You can have marble dirt, a pen stem, coin leaves, and a fresh picked flower in a unique, modern adaptation of the flower pot.
* Pens can be made into paper wad shooters for delinquent boys. Just remove the ink, tip, and clicker so you only have the barrel left.
