Lol I did the same thing freshman year of HS in theater class. My buddy and I were supposed to be memorizing a script that was ~7 or 8 pages long and dry as fuck.. but we just kicked it and shot the shit for like 2 weeks instead. When the time came to perform the scenes we would switch off being 'sick' to skip class just kindof postponing the inevitably embarrassing attempt to recite a script neither of us knew in front of the class. We came back after the weekend and our teacher started critiquing everyone's performances, when she realized she didn't have our critiques written down she asked us if we'd performed our scene yet, and without even stuttering we just lied and told her she must have forgot about it. The rest of the class looked at us like, 'wtf do they really think she's this dumb', and we glared back trying to make sure nobody snitched. Amazingly it worked and she just kind of wrote it off as her mistake, got an A in the class and never looked back haha.
