Here's an example with photographic evidence:
The following photo was taken at Carl and Toni's wedding. You've got (L to R) Miss Sally, Beth, Dana and Leslie. It was taken by Dana's husband, Rod.

Off camera to the left of Rod, is me. Back a little. (You'll be able to figure out the trajectory in just a moment.)
I cannot remember exactly what I said, but it was to Dana and Rod took this second photo right after I said it.
You can see from the photo that three of the four people in the photo found what I said to be amusing.

I sometimes think to myself, is being egotistical, self absorbed and selfish such a bad thing? I can answer only as one with those qualities can: of course it isn't such a bad thing... for me.
I end with the timeless words of Dana's grandfather Mike, "I love me. Who do you love?"
