A TV presenter of "Who Wants to Be a Millionaire" lamented it would be a "jolly weezer" if the man made less than his wife on a game show. What did he mean?
One meaning of wheezer is a bad joke - it makes you wheeze instead of laugh.
3. a wheezing breath or sound.
4. an old and frequently used joke, saying, story, etc.
A possible implication is that it would create a situation that they will never live down.
It was probably not weezer but whizzer which the OED defines as "Something or someone extraordinary or wonderful; a ‘stunner’. slang."
Their examples range from 1888 to 1977 but it is common for old-fashioned slang to be used for humorous reasons.
While it means a good thing, it could be used sarcastically to mean a bad thing, or it could be taken as a good thing from the point of view of his wife (or even from the point of view of his marriage, i.e. not upsetting his wife).
