So there is an episode of NCIS, previously mentioned, in which McGee wears an MIT t-shirt. During the filming of said episode, Sean Murray noticed in the mirror that his shirt spelled "Tim", which is his character's first name. Apparently, Sean Murray was quite excited about this.
I had a similar experience the first time I wore my brand-new AIM t-shirt; in the mirror, "AIM" spells "MIA", which, for the acronym-impaired, stands for missing in action. At the time, I laughed hysterically at how appropriate it was. And there has been nothing in the intervening 12 years to change my mind about that.
