Friday Night Out

Kamau is a hard worker, and he spends most of his evenings after work playing pool or watching the EPL.
One weekend, his wife decides that he needs to relax a little and take a break from sports, so she takes him to New Florida for a night out.
The bouncer spots them and says 'Ehhh Kamau? Mambo?'
His wife, surprised, asks Kamau if he has been here before. 'No, no. He's just one of the guys I play pool with.'
They sit down, and a waiter approaches, sees Kamau and says 'Vipi Kamau? Pilsner baridi kama kawaida?'
His wife's eyes widen. 'You must come here a lot!'
'No, no' says Kamau 'I just know him from choir practice.'
Then a girl, dressed to kill, walks up to the table. She throws her arms around Kamau and says 'Kamau, umepotea sana!'
His wife, fuming, collects her purse and storms out.
Kamau follows her and spots her getting into a taxi, so he jumps into the passenger seat. His wife looks at him, seething with fury and lets Kamau have it full blast.
At this, the taxi driver leans over and says 'Sure looks like you picked up a fucking bitch tonight, eh, Kamau!'
