In this case, here's a little contribution to this topic :
"La danse de ta plume chatouille mes sens" (The danse of your nib (feather) tickles my senses )
and some very classic french pick-up lines adapted :
"Vous écrivez toujours chez vos parents ?" (do you still write at your parent's ? should be do you still live at your parent's)
"T'as de belles courbes, tu sais" (you've got beautiful curves, you know. Should be you've got beautiful eyes)
" J’aime deux choses : toi et la (Brause) rose. La rose pour un jour et toi pour toujours" (I love 2 things : you and the (Brause) Rose. The rose for today and you forever...)
And a last one :
"You must have fallen from the Universal Penman"
