I'll admit, I actually thought the GMail custom time feature was real, at least initially. For two reasons:

1. I didn't read the entire explanation on the page. Had I originally read the bit about the flux capacitor, I would have chuckled heartily.

2. Something like that -- along with the totally arbitrary 10-times-a-year limitation -- is something I would completely expect from Google.

In other news, only one of my coworkers bought my faux letter of resignation. I guess I just wasn't convincing enough.
