Is this legal??

At any time a player may expose their cards. A player may play an entire hand while cards are exposed. There are no rules that bar you from showing your cards and no rules that say you may only show them at a certain time.

I believe it depends on the rules of the particular room you are playing at. In most all cases, it is a breach of poker etiquette and is usually an illegal play in most rooms. Check Roberts Rules, I'm not sure if it is in there or not.

You are probably one of those fools who does it. Wouldn't suprise me.
