You may have heard this one; then have a second grin.
Egg on face!
A young businessman has just started a company. He rents a beautiful office and fills it with expensive furniture. Sitting there, he sees a stranger walking into the office. Wanting to seem important, the businessman picks up his phone and pretends to be discussing a big deal. He mentions huge figures and a grand plan.
Finally, he puts the phone down, lights a cigar, blows a puff and asks the visitor who stands by waiting patiently, 'Can I help you?'
'Yes, I'm from the telephone company" the man replies..."I've come to activate your phone line.'
