Use the brain, atleast!

While at Navajeevan, Vizag Fr TV asked me if I was interested in using an original fountain pen. I had no such intentions at all. My Rs 1.50 pen works perfectly well with me and I with it. However, what was interesting was our struggle to see where exactly does one fit in the ink cartridges provided with that! I was carefully trying to see the pen, its interior and what not. TV looked around and just jammed it up the refill cabinet! That was it! And then he repeated his father's quotation:

If you cannot use anything atleast use your brain.
