The friendly in class game which involves competing with friends to see which participant can remove one's shirt completely and then replace it as quick as possible, without the teacher/lecturer/tutor noticing.

- If you are looking for a challenge, try completing a set challenger during the time period in which the shirt is removed. For example: Dancing.
Lachlan: Hey Mitchell! Want to play the T-Shirt Challenge?
Mitchell: Yes... Maybe after we can try playing the Song game!
Lachlan: Okay. Man, we should probably do some school work..

Mitchell: I already have guarenteed entry to Uni..

Lachlan: Okay.
