Definitely, I tried it myself. Not sure about the TEETH (teath?!) thing though as all mine fell out when I was 11 as a result of an accident with a bag of sherbet lemons.
A "cheak" is in fact a traditional teapot used in parts of Yorkshire. Hence the classic dialogue from a much beloved show:
- Get away wi' yer! Me cheak's on t'boil! - Aye, Nora lass, and it ain't t'only part neither! (Degenerates into comic brawl as Foggy and Clegg look on indulgently)
