As soon as I said that, everyone else couldn't believe I snuck it in there and altered my favorite saying, but since I saw Nancy from the back just waiting for me with an officiant's suit on hand, I just chuckled about the whole situation before going with the flow from everyone else's.
But yeah, a few others didn't even think we'd have a surprise wedding from the get-go—since everyone was still wearing casual clothes—but Allan and Jenny didn't want a grand wedding but a very simple one with all of our friends and family in one place.
It's just that I had to improv a few lines from memory but aside from my "group" chuckling to themselves from discovering the references I made along the way, all that mattered was telling the groom to kiss the bride and enjoy the happenings as all hell let loose when their lips touched.
