okay, i totally got this:
first, get on an airplane, with a parachute, the ring, and some flowers, and a kitten. THEN, fly over her place of work, and parachute down, crashing through the window and into her office/drive-thru line/whatever. give her the kitten, it will keep her occupied with its cuteness for a few seconds while you rip off the skydiving apparel to reveal a full perfectly pressed jet black tuxedo. make sure to wear an insane amount of hairgel as well.
THEN, give her the flowers, get one one knee get out the ring and say 'baby, imo get mine, and das you, sugah'. now smile real cheesily and wait for her to go 'Ohhh my goddd!" and cry and what not. now, you cue the band to come in and play music and everyone cheers. you run outside to the white stalion you had prepared and you both ride off into the sunset.
