hey i got another one.(this time i get the credit)
i dont know if someone already pointed this out before.
this is from
Smart Kids its the scene where Clark is playing table tennis (w/ himself)
then he hit the ball too hard, breaks some glass off-screen
he looks on the wall clock
then walks over to the livng room.
notice he is wearing gray(?) (blue-gray?) cut-off t-shirt while he was playing
but as soon as he goes to the livng room
the shirt magically has sleeves.
it doesnt look like he just pulled the sleeves up to play table tennis and pulled it down after.
thanks for the welcome Emrys.
