funny you should mention dolphins.
wuz flyin just this evening with sling, sally and osage when we notice osage was keying the mike silently... but every time he did; the dogs downstairs went nuttz..
sally explained it.. it was osage farting on his open mic... he remarked "only dogs and dolphins can hear his farts.."
..but that's another story; wouldn't wanna drag this jewel off topic.
