A blonde gets on an elevator

A blonde gets on an elevator.

When she entered, she says to a man that was

already in there,

"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 -- duuhhh
