one of my fave Sellers' films is 'The Party'

 I'm glad that you conjured a tear or two bayoubill. I sometimes try to cry just to see if I still can. It usually doesn't work. The last time was when my wife rented one of those chick flicks. I didn't want her to see it made me wet eyed so I tried not to cry then and it worked.

 Lack of sleep and hard drugs can also make that happen. I haven't personally tried the second one but I can attest to the first one after like 48 hours with no sleep you could tell me its time to eat and I get teary eyed.

 Reading some of the postys on here make me come close to it.
