Ways you have surprised your BF

Last week my bf and I decided we needed a little time off from each other (4 months) .... so if all goes to plan, after 3 weeks of no chat, I was going to show up to work and surprise him (and hopefully melt his heart) by giving him Valentine card "BE MINE" .... just got me to thinking, do you guys have stories about how you have surprised your BF in an elaborate/affectionate way?
