I'm glad you got to keep your job.
And offhand, this sounds like goodnatured joking and laughing, although I have a heck of a hard time telling goodnatured from mean spirited, and I think in fact, one often blurs to the other.
I think there are good general skills that can handle either one. For example, either a verbal or nonverbal "Okay" that you acknowledge it but it's not a big deal, the first time or two someone tells a joke. If they keep repeating it (which is actually an aspie style of communication! But obviously not unique to aspies) just ignore it.
(if it continues to be a problem, which in your case doesn't sound like it's going to, perhaps the method of talking to the person, 'I don't want to report this. But I will if it continues to be a problem.')
In your case, they sound like alright blokes. Is that the right way to say it? I'm from the States.
