DUI 

One night a police officer was staking out a particularly rowdy bar for possible DUI violations. At closing time, he saw a fellow stumble out of the bar, trip on the curb and try his keys on five different cars before he found his. The man sat in the front seat fumbling around with his keys for several minutes. 
Meanwhile, all the other patrons left the bar and drove off. Finally he started his engine and began to pull away. The police officer was waiting for him. As soon as he pulled onto the street, the officer stopped him, read him his rights and administered the breathalyzer test to determine his blood-alcohol content. 
The results showed a reading of 0.0. 
The puzzled officer demanded to know how that could be. The driver replied, "Tonight I'm the designated decoy." Deputy Gomer 
The local sheriff was looking for a deputy, so Gomer - who was not exactly the sharpest nail in the bucket went in to try out for the job. "Okay," the sheriff drawled, "Gomer, what is 1 and 1?" "11" he replied. 
The sheriff thought to himself, "That's not what I meant, but he's right." 
"What two days of the weekstart with the letter 'T'?" "Today and tomorrow." 
He was again surprised that Gomer supplied a correct answer that he had never thought of himself. 
"Now Gomer, listen carefully: Who killed Abraham Lincoln?" Gomer looked a little surprised himself, then thought really hard for a minute and finally admitted, "I don't know." "Well, why don't you go home and work on that one for a while?" So, Gomer wandered over to the pool hall where his pals were waiting to hear the results of the interview. Gomer was exultant. "It went great! First day on the job and I'm already working on a murder case!"
