Acknowledgements in a bachelor thesis: Is it etiquette conform to thank for non thesis related things? As I'm about to finish my bachelor thesis, I'm at writing the acknowledgement section.

How far can I go here in terms of non-thesis-related stuff? 
Is there room for humorous acknowledgements (like thanking my coworker for his great taste in music or bad puns), or is that rather something to be left out?
The acknowledgment part is your own part, write what ever you want in humour, fun etc but don't cross the boundaries that might hurt some people feeling. here is a sample from MIT, you can give a read.
