Do coworkers make jokes out of another coworker's strengths?

For example, while I am using a microscope, coworker tells me "don't break the tool". This annoys me as I take my job very seriously and have a very strong desire to do a good job. I have confronted another person who has done this, and they have apologized saying it is a joke, you wouldn't break the tool. But, I don't understand it. To me, the people doing it like to get a rise out of me. People know that I can be a bit insecure/anxious. I never smile/laugh when people say those things to me (has happened multiple times, but for other tools too - for example, for another tool that was down, someone said did you break the tool again?), so why repeatedly 'joke' about things like this? I don't understand the humor. To me, they get some satisfaction from trying to make me feel a bit uncomfortable/insecure. I am also a bit of a perfectionist. I would really appreciate input from different perspectives on this...
