This is the best pick up line - it works best if you have a sense of humor and you're not afraid to use it.
Also, you need a prop - you will need a packet of sugar that says "sugar" on it.
Step 1: walk up to your person of interest
Step 2: tap them on the shoulder
Step 3: when they turn and face you - hold out your hand with the sugar packet in your palm with the word "sugar" facing them and say "Excuse me, you dropped your name tag"
Step 4: smile :)
