Silly riddle I can't figure out.

I got sent this riddle, and I can’t make out what it is.

I told you that one b4 huh ok einstein!

Best I can figure is that the first line is something like one 2 B or something, but can anyone help a Wonko out?

I told you that one b4 huh ok einstein!

1bb
------ = 3now
1bs
Let me know if you give up!

Sorry for the inconvenience!

1 baffled baboon divided by 1 brown sock equals 3 nifty orange wraps.

How’d I do?

Looks like a racist joke I heard a long time ago. The easily offended should look away now:

One black brother on top of one black sister equals three niggers on welfare.

disclaimer: look, I didn’t WRITE the damn joke, okay?
