My students suck at plagiarism.
I mean, I know it's good that it's easy for me to catch it, but at the same time I can't believe how stupid they are when going about it. Don't cut and paste directly from websites! Do you know how easy it is for me to find that website? So easy! Plus, when the other student are heckling your presentation because of how badly you plagiarized, you better not deny it when I confront you about it later. That just makes me mad, especially if you show no remorse, which means you won't get a chance to make up the big, fat zero you will be getting on this month-long research project.
