Years ago a biker friend of mine got married, I was takin pix at the wedding for them. He being totally unfamiliar with the whole cut the cake thing was completely taken by surprise when she shoved a piece in his face (egged on by her bridesmaids). His reaction was much like the catapult, he decked her. Now he wasn't decking her, he was a biker and when 'attacked' went on autopilot and his fist simply backtracked the direction of the blow received. His face lit up in horror when he seen what he was done, but also in confusion as to why his bride just hit him...
I got it all on film.
He got her good, she swole up quick with a bloody nose, twas quite the moment, his family...bikers...her family actual kin...it got settled quite quickly.
Another fun wedding, was by two who met playing softball. Nuptials with the Rev on the pitchers mound and us in the bleachers the game started up, with everyone in tuxes and dresses as soon as the rings were on. Sliding into second, diving for line drives, collisions at home, and the champaign of beers on tap behind the fence...whatta wedding.
Bullwhips are great, but a nice usable cat-o-ninetails might be better, or a leather hair tie from the past....
