similar to chmlover in some ways...
...you make a bonding theory for people using chemical bond types (just did this yesterday). (ie the people who are friends, different personalities, are hydrogen bonding; ionic bonds are those lovers with opposite personalities; covalent bonds are the more partner-like couples or friends; etc
I went off to polar and polar covalent too...)
...you see something and you can make a chemistry-related joke about it.
...you think the most hilarious question to ask a person is what their bonding type is because it sounds like such a come on or else it's the most hilarious pick-up line you've ever heard (well, you know the other chemistry ones, they're quite amusing too
...you've told someone that you've wondered what a molecule's perspective would be and someone looks at you like o.O Really...wouldn't a molecule consider the human body the universe just as we consider the universe the universe? If it could be conscious?
...your sense of humor goes *downhill* as you progress.
