Friends say it's strange — even actor gets married (6)
I believe the answer is:
sitcom
'friends say' is the definition.
(Friends is an example)
'it's strange even actor gets married' is the wordplay.
'strange' indicates an anagram.
'even' means one should take alternating letters (even-numbered letters are used).
'gets' means one lot of letters go next to another.
'married' becomes 'm'.
The alternating letters of 'actor' are 'co'.
'its' anagrammed gives 'sit'.
'sit'+'co'+'m'='SITCOM'
(Other definitions for sitcom that I've seen before include "Light-hearted TV series" , "Friends, for example" , "Form of TV comedy" , "Type of comedy show" , "Shortened form of situation comedy" .)
