you're doin' just fine without me, hev. (wassamatta, you don't like Quinion's take?)

Yeahbutt® I didn't have the OED to quote from... tsuwm sent me this info in PM and I post here with his permission.

"interestingly, the phrase 'suck eggs' turned up ten (10!) hits in the OED.

here is the earliest citation (prolly same as Quinion)
1707 J. Stevens tr. Quevedo's Com. Wks. (1709) 348 You would have me teach my Grandame to suck Eggs."

Thanks tsuwm (and the OED)!
