Steve,
Speaking as someone who had to be resuscitated from drowning, I can assure you that it's a good, nearly painless way to go.
It doesn't hurt. Just inhale the water as if it were mini-tacos.
There are several bonuses to a drowning for you, Steve. Firstly, you can't possibly look anymore bloated than you already do now. Secondly, it's free, and you libs are all about "free" stuff. Finally, it avoids leaving a big mess for poor suffering Marta to clean up.
Now if you wanted to change it up a little bit, you could go out with a bang. I'd recommend waddling down to the sewage plant and asking them if they'll let you drive your little catbird seat out over the incoming vat of sewage one last time. When you're out there, jump!
