There's an iPhone app called Progress to 100 where the aim is to do various quick levels by replicating what the app tells you to do on the screen. Sure enough, level 59 is "tickle me" and the woman doing the audio (no visual) laughs hysterically. You can imagine my shock when I had overheard some people playing this game back in 2015 when it came out, so it took me forever to find it. There are a couple walkthroughs of it on YouTube. I'll link one where the guys take forever to complete the stage.
