A business man got on an elevator.

When he entered, there was a blonde already inside who greeted him with a bright, 'T-G-I-F.'

He smiled at her and replied, 'S-H-I-T.'

She looked puzzled and repeated, 'T-G-I-F,' more slowly.

He again answered, 'S-H-I-T.'

The blonde was trying to keep it friendly, so she smiled her biggest smile, and said as sweetly as possibly, 'T-G-I-F.'

The man smiled back to her and once again'S-H-I-T.'

The exasperated blonde finally decided to explain.

'T-G-I-F' means 'Thank Goodness It's Friday.' Get it, duuhhh?'

The man answered, ''S-H-I-T' means 'Sorry, Honey,
It's Thursday'
