'natural history man on tv' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'may be mad bad lively' is the wordplay.
'may be' indicates anagramming the letters.
'mad'+'bad'+'lively'='madbadlively'
'madbadlively' anagrammed gives 'DAVID BELLAMY'.
