We were forced online for this session and during the classic "Wait, I can't move my token" "Here, let me sort this out for you" moment, I realized I had control of... a torch.
During my last R20 D&D campaign, the DM gave me a bunch of spell effect tokens so my wizard could accurately mark where spells hit. During other players turns, I'd have lil conversations between the wizard and his spells in chat.
It was good silly fun, thanks to Roll20's bizarre design choices.
