Science Week Joke- Day 2 & 3

So I know I promised a joke a day for 'Science Week' but Uni has caught up with me and I forgot yesterday...So therefore I will give you 2 jokes today

1. My name is Bond, Covalent Bond!
2. My name is Bond, Ionic Bond; Taken, Not shared!

If you don't understand I highly suggest you watch a James Bond movie...oh and learn some chemistry :)
