Bert,
I all too often get a hopeless case of the giggles. Tears run down my face, I shake in an attempt to control the outburst, and in general make a fool of myself. But I feel so good when it is over. Does this mean I use more of my brain than most people?

For those of you using public transportation, these "fits" guarantee a seat and sometimes even an entire subway car to oneself.
