Two junior co-eds, Judy and Fern went to the movies one night. 
 
 Fifteen minutes into the movie Judy leaned over to Fern and 
 whispered to her friend, "What should I do? The guy sitting next
 to me is masturbating." 
 
 Unable to tear her gaze from the movie screen Fern whispered back
 "Don't do anything, just ignore it." 
 
 "Believe me Fern" retorted Judy somewhat indignantly, "I wish I 
 could ignore it but I can't." 
 
 "Oh why not!" hissed back Fern.
 
 "Because he's using my hand!"
