Is THAT what is was??
I thought it was wall cavity sealant!!
Anyway, the Doctor once swallowed a full size snooker ball. Whole.
He said he had gone from feeling in the pink to green the next day, couldn't help fill his pockets and had to wait in a big Cue at the hospital when the ball started to foul his insides.
Once on the table, the doctors got him to swallow a Cue ball which soon sorted it out.
