How do you write the 8 number... two circles or one movement?

3. Flat top, round bottom.
5. Flat top

I have never ever seen a 3 with a flat bottom.  And I don't know if I've ever seen a 5 with a round top drawn on purpose.

 

My 5 sometimes look like a S, and something it has almost no top at all. Never seen a 3 with flat bottom, that sounds weird.
