Husband : So you finally found those shoes you wanted!
Wife : No, but these are better, I got them on sale
Husband : Oh Good! How long do you think they will last you?
Wife : The salesman said they will give at least 500 miles jogging
Husband : How can they say that? They would have to take in the condition of the road you jog on, your weight, the weather and a bunch of other things!
Wife (cold freezing tone as opposed to happy excited voice of moments earlier) : I have no idea
Husband : Totally oblivious to the chill in tone : So do you think you will get 500 miles out of those?
Complete cold silence …
