I went for a flight last night...it was a gorgeous night baytour for a co-worker and her boyfriend. I had just taken off from RHV and I got the usual handoff to SJC Tower. I made my call...Evening San Jose Tower, Skyhawk 53614 just off Reid-Hillview climbing through 1000' VFR Baytour; I got the usual Cessna 53614, cross midfield at or above 2000', altimiter 29.9* response. After I read that back to SJC, I heard a quick "ree-shard" over the radio.
It's kind of cool getting recognized by your pilot friends who just so happen to be on the same freq. as you.
