A contractor is working on a roof when a blonde walks by. She smiles at the guy and in a perky voice says, “T.G.I.F!”.

The contractor looks at her and replies, “S – H – I – T.!”.

The blond’s smile falters a bit as she digests the contractor’s response. Then she smiles her biggest, friendliest smile and says, “T.G.I.F.!”.

Again the contractor responds by saying, “S – H – I – T.!”.

The woman is obviously quite upset and asks the contractor, “Don’t you know that T.G.I.F means Thank God Its Friday?”.

The contractor says,”Yes I do, and S – H – I – T. means Sorry Honey Its Thursday!”.
