Doug loses his journal
Roger is the one that found it
Returns it but makes a joke about how he can't even read it because of how shitty and illegible it was
This guy was more based than I remembered. Roger probably could read it but just didn't give a FUCK what was in the journal. Roger could've just burned it (though he wasn't a firebug, maybe rip out the pages and flush them down the toilet, put the pages in Stinky's litterbox, etc) or just not even return it at all. It was Funnie's property, not his.
Roger probably thought Doug was super conceited for even thinking he would.
