Gimme a break!
1) I am apparently not THAT old
2) I hardly consider BS that profane or obscene
3) This language was not used in "public" it was written at the bottom of a check.
I have seen and heard profane and obscene language used in public - on the streets of our nations capital to be exact. I find signs and chants saying, "F--K Bush" and "Bush $uck$" far more offensive than BS written at the bottom of a check that 99.9999999999999999999999999999999999999999999999999999% of the country would never see.
1) True, you aren't that old
2) BS was considered obscene language at that time
3) Yes, that's public enough
