I set my phone calendar to alert me at 9:40 am that I need to check the mice today. On my way to work, I remembered anyway and erased the calender item.
At 9:40 am, a ring tone that I've never used (one of the upbeat phone ones) alerted me to an event scheduled. The event?
Name of the event: several "y"s with umlauts (taking up the entire line)
Dates/times: Oct 13, 13652 7:63pm to Feb 31, 4095 11:59pm
Repeated End Time
Until Feb 31 4095
Also, this isn't the first time this has happened. It did the same thing last time, but that was months ago and I didn't write it down for posterity.
