Well there are various ways to handle such a situation.
1. If your boss is the same sex as you are (or if she's a female) always compliment their clothes, women especially shoes, compliment guys on their tie or coat.
2. Always ask after their family.
3. If he is late, call him from the office showing concern that he's late.
4. Remind him to have lunch/breakfast
But, if he is not your direct boss then always try to avoid him, don't be too much in the lime light wherever he is.
this is just the few advise i can remember for now.
I hope/believe this would work.
