Put your head in a wall

From Glitches

From the game Chameleon Twist 2 for the Nintendo 64.

Go through the second level. You'll get to some walls that go upwards and stay up once you reach them. Try standing close to the walls and sticking your tongue inside of them. Your tongue will sometimes attach to something inside of the wall and drag you in, pulling your head inside the wall.
