How often do you allow yourself to be silly in your work?🤪

Especially on Social Media, we have plenty of examples of brands that allow a certain silliness factor. Like the twitter feuds between Wendy's and Burger King, Pepsi and Coke, and Netflix's excellent spicy humor. 😂 B2B companies are usually more serious. Supposedly to create trust. But I think a giggle or two can be pretty trust-building.🤗 What do you think?
