A pot of coffee or tea
A taglock representing yourself - fingernail, a small hair, dried skin, etc.
Take your taglock and grind it up into a fine powder. Mix it in with your target's coffee or tea, and serve it to him. He will soon find you irresistible. If you're really squeamish about the whole "bodily items being ingested" thing, write your name or initials with sweetener or creamer in the cup before pouring.
