“Why are you bummed out...this is the best weed we've had in months” says the friend.
“No dude, the weed is great. It's my wife. I just found out she's a liar.” replied the burnout.
“Wow...how did you know?” asked his friend.
“She never came home last night and when I asked her where she was she told me she stayed the night with her sister Mary.”
“So what” said the friend.
“That makes her a liar. I spend the night with her sister, Mary.”
