Strategically, I would think playing "a little crazy" would be best among players that know you. Assuming that you have the NITiest image with them.
Generally live or online anonymous or not, I like to sit back and get a feel for what people are doing at the table, before I decide my line of play.
Maybe if you have this deep psychological need to get crazy, before you play live or online, you could strip naked and run around your neighborhood before you do. Or just in your underwear for just a "little crazy"!
