This reminds me of a joke i heard one time.

Last year i was in the library and a russian girl came up to me and asked me...

Ручка есть?

Even though she was very pretty and i wanted nothing more than to help her out i didnt have anything to write with so i answered with a reluctant

не...

Then she smiled and asked me

А ножка... есть?

HA HA HA GET IT? Hahahah Yea i thought that was pretty clever.
