Hilarious.

…I did learn a few useful things…

Older people are much less likely to see the funny side of something, even when the safety of the universe is in the balance.

Couples are far better at avoiding the magically hindered than individuals.

Men with grey beards really don’t like to be called, “fellow wizard.” (Although, their wives are likely to find it funny.)
