Took a long time to propose to fiance (now, groom speech!)

30 year old guy who took 10 years to propose to fiance. I know I know, too long... but not ill-intended and I just love her more now!... There will be inevitable jokes on it. Any ideas how I can deal with this classily/wittily/light-heartedly in my groom's speech? Keen to hear any ideas/jokes you've heard.
