My first "real" baptism - even after practice - was a 6 foot 4 inch 330 pound truck driver named Joe. When I went to lower him into the water there was a wave that splashed over the baptistry into the choir loft....and then I dropped him! Struggling to get him back up out of the water and say the right words while doing so drove his girlfriend to stand up and say a very loud AMEN when it was all over.
It was funny because before the baptism "back stage" if you will, he said to me, "If you drop me I am taking you down with me." Having a good relationship with him I replied, "No problem. You won't drown. Fat floats."
We laughed about it even more afterwards as I tried to convince him that he was dropped because he forgot to bend his knees, not because he was so heavy!
You see, one of the most important things to remind people when immersing them is that they must bend their knees. If they do not it is like lowering a stiff plank into the water and you will drop them, and likely fall over with them.
Thinking back, I stopped wearing waders when baptizing when we started holding our baptismal services at the lake. My first lake baptism when I lowered the candidate, I am so short that the edge of my waders dipped beneath the water level and my wader's left leg filled to the top with water. I had to pull them off in order to get out of the lake!
See......sprinkling cannot be as much fun as immersing. It just can't.

PS - my wife took pictures of a baptism not too long ago and they came out funny. There I am in the lake with the person being baptized. Then he is gone and it is just me standing there, and then there he is again all wet standing next to me.
