Be careful with sarcasm and teasing. Even if the intention is wholely innocuous some people react poorly and over time most people stop finding it funny unless they use the same kind of humour.
Sarcasm and teasing tread a fine line between humour and personal attack. Through personal experience I've learnt that the negatives of that form of humour outweight the positives. However it's a deeply ingrained habit for me, so I often find myself teasing someone even though I know they won't really appreciate it. I don't find that it helps in building relationships.
But it's fine as long as whoever the sarcasm or teasing is directed at enjoys it and joins in.
