This one might seem a little silly but...

I am thankful for companies with a sense of humor.

It's a little thing but it can seriously make my day.

I love it when I see an ad that is funny

Or some little bit of humor on a website

...nothing over the top...

just enough to show that these people know how to be funny

and understand a good sense of humor

I enjoy a good sense of humor

For example:

I enjoy using Groupons

I don't buy every groupon that shows up in my inbox but I can't resist clicking on some of the links because at the bottom of the groupon site is some little funny bit of advice.

The Groupon Guide to: Keeping a Secret

An old saying goes, "Three men can keep a secret, if they are best friends, and one of them is a cardboard dog." If you've been entrusted with a secret, consult this sure-fire guide to keeping it to yourself:

Think about the feelings of others. Especially their anger. You’ll likely avoid sharing their secret by considering your own predominant feeling: fear of their anger.

Seal your lips. Ideally with honey or room-temperature wax.

Find a healthy outlet. Some secrets are so juicy you just want to shout them from the rooftops. Instead, whisper your secret into a shallow vole's nest or speak it aloud at what would normally be an audible volume, were it not drowned out by a nearby car-crashing contest.

Share a secret of your own. Most modern friendships are based on a delicate balance of mutually assured destruction, hence the expression BFF, or Betrayer? Fairly foreseeable.
