I think it's a slippery slope trying to change your personality to become "the funny one" if you're not naturally a funny person. Personally, there are many other personality traits I'd be attracted to / interested in, before "funniness"... Funny people can be very shallow and dismissive of others (in a "funny way" of course) so I wouldn't necessarily be interested in befriending funny people... but that's just me of course... Besides, as another poster pointed out, what's funny for some people isn't necessarily funny for others... Be spontaneous...
