“They asked if I could sing tenor—ten or twelve miles away”

“Tenor” sounds like “ten or.” A joke was told on the comedy television series The Muppet Show on September 17, 1977:
   
Statler : Can you sing tenor?
Waldorf : What?
Statler : Can you sing tenor, as in ten or eleven miles away from here?

   
“They asked if I could sing solo—so low they can’t hear me” is a similar joke.
 
     
Wikipedia: Tenor
A tenor (from Latin tenor - holder, or tenere - hold) is a type of classical male singing voice whose vocal range or section is higher than baritone and lower than countertenor. A person, instrument, or group that performs in that range or the tenor clef is also called a tenor

There’s a bubble gum wrapper joke that goes something like this:
 
First man (annoyed by and speaking to another man singing flat and off key)—“Can you sing tenor?”
Second man—“Why, yes, I certainly can.”
First man—“Good. Do me a favor and sing ten or 20 miles away.

 
OK, nobody said bubble gum wrapper jokes were funny or good.

Then sing ten-or twelve miles away.
A classic put-down of my singing from my Dad. R.I.P.

I didn’t want to do it, really, but with his incessant whining I had no choice. So yes, I cannot sing, but enjoy and laugh at his and my expense.

You know, I’m such a good singer, people always ask me to sing solo
......solo they can’t hear me.
Coincidentally, they also ask me to sing tenor.
