A man drinks a shot of whiskey every night before bed.

After years of this the wife wants him to quit, so she gets 2 shot glasses, filling 1 with water the other with whiskey.

She gets him to the table with the glasses and has his bait box there too.

She says I want you to see this. She puts a worm in the water it swims around. She puts a worm in the whiskey and the worm dies.

She says so what do you have to say about this experiment?

He says IF I DRINK WHISKEY I WONT GET WORMS!
