Good one!
Similarly, After I beat a sport bike off the line at 3 traffic lights in a row and stayed ahead for about half a block each time until he came screaming past me with after-market pipes wailing, I said,
"That was fun! How many cc's ya got?"
He replied,
"One thousand. And you?"
I held up my hand, and touched my thumb to my forefinger,
"Zero."
[Aren't electric bikes fun?]
