During the last Splatfest, I was using the Nozzlenose and hit two enemies with a Disruptor, then whipped out the Killer Wail and nailed them with it since they couldn't really get out of the way. It was a fun, if impractical, double splat (we won that match, too).
Also, during a regular match on the Mall, we were getting pushed back and I managed to get into the centre. There was an E-Litre at the top of the ramp, and I just started walking towards him without shooting. He backed up enough to fall off the edge and into the water. It was pretty funny, though we lost the match. Totally worth it, I'd say.
