UITableViewCell selector setSelected:animated: gets called many times?

I've discovered a strange behavior with setSelected:animated: in my custom UITableViewCell class. I discovered that this function gets called multiple times if I click on a cell in my table. I am wondering if this is normal behavior or a bug in my code.

To help with debugging, I've modified the setSelected:animated: function in my custom UITableViewCell class implementation as such:

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {

[super setSelected:selected animated:animated];

// Configure the view for the selected state.
if (selected)
    NSLog(@"Yes %X", &self);
else
    NSLog(@"No %X", &self);

}

If I click on a cell in the simulator, here is what I get in the console:

2011-03-22 22:05:26.963 marketPulse[3294:207] Yes BFFFDDD0
2011-03-22 22:05:26.964 marketPulse[3294:207] Yes BFFFDE30

You would think that I would get only 1 entry, since I only clicked on 1 cell.

And if I click on a different cell after that:

2011-03-22 22:07:11.014 marketPulse[3294:207] No BFFFD890
2011-03-22 22:07:11.016 marketPulse[3294:207] No BFFFDD00
2011-03-22 22:07:11.017 marketPulse[3294:207] Yes BFFFDDD0
2011-03-22 22:07:11.017 marketPulse[3294:207] Yes BFFFDE30

If I click on the same cell 2 times in a row, I get more than 2 Yes:

2011-03-22 22:08:41.067 marketPulse[3294:207] Yes BFFFDDD0
2011-03-22 22:08:41.068 marketPulse[3294:207] Yes BFFFDE30
2011-03-22 22:08:41.069 marketPulse[3294:207] Yes BFFFDE30

The more times I click the same cell, the more Yes I will get, and if I click on a different cell after that, I'll get a lot of No

I put a breakpoint before the NSLog, and looking at the debugger, it seems that all the repeated calls are coming from the same object.
