WHAT IS THIS?

I have a mystery plant here... Anyone know what it is?

I will be super embarrassed if it is a weed as I have already transplanted it into a prettier spot! :p



UPDATE

Well the two suggested identifications were Stinging Nettle and Catnip... So who do I use to test what plant this is, me or the cat?

It is Stinging Nettle, a pretty plant with lots of uses (anyone ever had Nettle Soup?) so I think I will keep it- but relocate it to a location where the kids don't run through it every day!

And no cats were harmed in the identification of this specimen....
