The Perfect Alibi
Two friends are sitting in a bar, and one says, “I don’t trust my wife anymore. She’s been acting suspicious.”
The other friend laughs and says, “What are you worried about? If anything happens to you, I’ll vouch that we were here all night.”
The first guy looks confused and says, “Wait, are you saying you’ve thought about this before?”
The second guy grins and says, “No, I’m saying you should’ve thought about it before marrying her.“
