What you did last night was bowling. As opposed to "tenpins". This is like when you talk to Heather Williams and "hockey" comes up. She will point out that hockey is played on grass, and what the Boston Buins play is "ice hockey".
(Lame scores, though, dude... sorry I wasn't able to get there...)
(And how did you get 22 points out of a spare?)
The sum of the last two frames was 22. I guess it was spare, 511 or something.
