Which SNL Gilda Radner character and episode title is the attached quote from?

I'm trying to recall the identity of a Gilda Radner skit where she digs out an eye "booger" and starts talking about it, saying stuff like, "You know that little thing in the corner of your eye, you dig it out and roll it around between your fingers and then it disappears? What the heck is that?"
Or something like that, anyway.

I can't remember if the character was Emily Litella or if it was Roseanne Roseannadanna, or another character entirely.
I want to see it again really badly and can't figure out which character, episode, or skit name it appeared in.

This was back in the 1970s, so I know this question may be a long shot, but I'm asking for your help. Thank you..
