Well. It is a harmless joke. I get the idea and find it partially funny. Its another thing if people comment negatively about her age, this is just tongue-in-check. But the Cher-jokes are funnier, mostly because she's really been around forever and looks almost the same and she seems to be in for the joke too.
Except, Paws Down is a Lady Gaga hate site dedicated to making things up about Lady Gaga. Jankyass is not a Madonna hater and doesn't run a Madonna hate site. Stop with the false comparisons to try and victimize poor Madonna.
