Have you ever licked a battery?

WTH ? Such a weirdly random question...lol.

9 volts... Yes, that's how I test them.

Nope.

I have tested 9 volts on my tongue.

Heck no!!! Not my job!

Yes

Once.

I just did and I must say I feel supercharged.

Yep ... Tingly and a very distinctive tangy taste.

If I said I could test a "D" cell as well as a 9 volt would that make me special?

No..... Just no. 😮
