"T.G.I.F." vs "****"

A blonde lady and a man are in an elevator. The blonde obviously just ending a hard day of work and says, "T.G.I.F." The man sort of laughing and says, "****" The lady frusrated says again, "T.G.I.F." Again the man says, "****"

The lady turns to the man and says, "How dare you swear in the presence of a lady! T.G.I.F.; Thank God It's Friday." The man turns to her and says, "I wasn't swearing! ****; Sorry Honey It's Thursday."
