A whole bunch of us were sitting around my house talking and we 
were trying to remember a guy's name. None of us could remember 
his name at all when all of a sudden my friend yells, "Dick!". 
We said yes that's it. Then she said "Boy, I pulled that one 
out of my ass". No one said anything until I burst out laughing 
and she said "You had to go there didn't you?"

Once in a diner, I wanted a Ham &  Tomato toasted
sandwich.  After about 10 minutes the waitress came back
and apologized.  "We don't have Ham and Tomato toasted
sandwiches but you can have the  'Special'."  I asked
what was in the Special.  "Ham, Tomato, Cheese . . . "

Prof. Lachner once taught a class from 2:30pm to 5:30pm. Every time the
class met, all the students would have a lot of food on their desks when
the class started. During the 5 minutes break, all of them would line a
queue at the nearby vending machine. He couldn't understand why these
students were hungry all the time, anyway, his class was just after the
lunch time and long before dinner time. Prof. Somebody was not happy about
this because when they ate, they make a lot of noise. So he announced one
day "No food in the class". Next class he found the classroom extremely
quiet. Guess what, everybody was dozing because nothing was keeping them
awake.
