I got Paul a Nerf Maverick six-shooter as a Christmas gift this year. It's awesome!
We went out and bought a second one for me recently, and have been having sweet duels and shoot outs. It's super fun, and a great way to beat the already encroaching cabin fever. I would say its some of the best entertainment I've ever bought for less than $10.
What do you think? Should we take it to the next level and start modding them? Some people out there are real intense about their Nerf guns and paint them to look all steam-punk. Crazy!
