Alright, listen up, buttercup. This ain't rocket science. DYM probably stands for "Does Your Mother..." and 101 is like the intro class. The joke is the setup and then you have to supply the punchline yourself, like "Does Your Mother know you're wearing her clothes?" Get it? Probably not, you seem kinda slow.
