“A blonde woman gets onto an elevator and she says to the man on the elevator 'T.G.I.F'

The man replies 'S.H.I.T.'

She furrows her brow and repeats 'T.G.I.F.'

The man replies once again 'S.H.I.T.'

The blonde says 'T.G.I.F.--Thank God it's Friday!'

The man says 'S.H.I.T.--Sorry Honey, it's Thursday!'”
