Feeling Unincluded

So I have some people at work whom I consider my friends because I don't really have any at all and I'm close to a few of them. Problem is, I don't really do the stuff they like to do so I feel like they can't or don't include me in anything. Like I can't legally drink, I don't smoke cigarettes, and I don't do drugs. Plus I'm a little cautious because of my anxiety so I don't do anything with them like pranks. One time we plastic wrapped our bosses car and I kinda stayed on the sidelines because I was afraid I'd lose my job (I didn't and my boss thought it was hilarious). But the thing is, I don't want to hang out with people who are like me because I feel like I'm no fun so "find friends with the same interests" is not the best choice for me. What can I do?
