One with twenty-two legs? (6)

I believe the answer is:

eleven

I'm a little stuck... Click here to teach me more about this clue!

'legs?' is the definition.
(eleven is 'legs eleven' in the game bingo)

I can't explain the rest of the clue.

(Other definitions for eleven that I've seen before include "Football or cricket team?" , "Number on a soccer team" , "Cricketing side" , "'Legs' bingo number" , "Not first team (6,6) - See 24" .)
