Hang on a mo' how can mass change with time here?

Ah, got it, currently sitting down having a tulip whilst reading this so I suppose my mass is steadily decreasing.

And assuming that you continue to expel mass which will not be a linear function, then you should tend towards your real mass.
That is:
Mr=Mrs-C
Where Mr is the mass in reality
Mrs is the starting mass and C is the amount of crap.
So if you subtract Mrs from Mr, what you have left is all Crap.

Edit: how did I manage to subvert the tulip filter?
