I need some advice on what could be a life changing decision.

I've suspected for some time now that my wife has been cheating on me. The usual signs. Phone rings, I answer, someone hangs up.

She started going out 'with the girls from work a lot recently although when I ask which girl it is always "Just some friends from work, you don't know them".

I always look out for her taxi coming home but she always walks down the driveway and I can hear a car driving off like she got out of the car round the corner. Why?

The other day I picked her cellphone just to see what time it was, she went ballistic and screamed that I should never touch her phone again and why was I checking up on her?

Anyway, I have never approached the subject with my wife. I think deep down I just didn't want to know the truth but last night she went out again and I decided to check on her.

I decided I was going to hide behind the Jeep which would give me a view of the whole street so I could see what kind of car she gets out of.

It was while I sat crouched behind my Jeep that I noticed a small crack in the center cap of my right rear wheel.

Should I buy new center cap from from the dealer or should I look elsewhere and find a nice set of rims?

Is this the most unexpected end to a joke ever? Brilliant, just brill...
