Bathtime
From Richiepedia
Richie overfills his baths and then cannonballs into them resulting in the whole bathroom getting drenched, then he preceeds to fall asleep in the bath so that no-one can use the toilet.
Richie also has an absurd amounts of toiletries, far too many for a straight male.
Despite what his housematess may say, Richie never 'cannonballs' into a bath. To do so would probably result in 3rd degree burns. Despite his best explanations, no one still graps that Richoie is 20, not 12. He enjoys a bath full to the limit, that he can sit and relax in, without fear of interruption.
