You can perhaps fake being smart, but there’s no way you can increase the number of brain cells you have (you can, however, kill a great amount through easy means like alcohol and drugs).

However, you can buy more neurons. They won’t help you get smarter, but they will look very cute. The Plushie Brain Cell from GiantMicrobes doesn’t do anything, but beside looking adorable it can spark intelligent conversation (if someone can recognize a neuron-shaped plushie, you know s/he’s worth talking to). But be prepare to answer comments about how your own brain cells weren’t enough so you had to get more…
