Where can I find an "ArcGIS Server Web Service" URL to load into my map?

What is a layer from the web that I can load via these options:
- ArcGIS Server Web Service
- OGC Web Service (WMS)

It wants "...ArcGIS/rest/Services/..." in the URL but any links like that that I have found via google are not accepted in the ArcGIS dialog box.

I get unhelpful error messages like this: "The layer, ESRI_LandBase_WebMercator, cannot be added to the map."

I'm just trying to find ANY layer from the web that I can load via those options; I don't care what it is as long as it works. I have done CSV and KML fine, but don't know what I'm looking for for the others.
