Have your co-workers or classmates been goofing off or gone on vacation too long and you’re ready to play some pranks on them when they return? How about replacing all their desk tools with LEGO versions, like these nifty replicas by Chungpo Cheng? With a glue stick, hole punch, and pen, Chungpo has all the things a teacher or accountant could want (don’t ask what an accountant uses a glue stick for).

And in case that’s not enough, try out these scissors, eraser, pencil sharpener, and retractable box cutter. Although each build is simple technically, they all look the part perfectly. There are even pencil shavings in the sharpener box!
