Ideas for Boyfriends Birthday?

Something that would make his heart melt would probably be taking him out for a nice dinner and movie. A scavenger hunt sounds fun, but it may not be the best idea since it's freezing. When you take him to dinner, you should surprise him with a personalized Swiss army knife pen engraved with his name. I got one for my boyfriend for Christmas (he's 26) and even though it may not be considered a "romantic" gift, the extra thought you put in to his interests makes it romantic ; ) He'll use it everyday and it's a great manly gift too.
