one time at my school (not on april fools though) the 7th and 8th grade french classes piled 2 feet of snow behind this teachers car and we put giant ice chunks in between his tires and the body of the van, he was so pissed XD
me and a couple of my friends got my humanities teacher good...
hes like 80 and he taught my mom.. anways we got everyone in the class to show up late cause he flips if one persons late..so we ended up having to copy 5 dictionary pages each..
My teacher handed out these folders today for a class activity. They were yellow, but I wrote "Blue Folder" on some of them. She thought she was seeing things! lol
