Comic for 06/12/13

I found this script-conundrum interesting! Panel 4, balloon 3. Should it be:
1) “His last word was ‘boobs.’  He’d like that.”
2) “His last words were ‘boobs.’  He’d like that.”
3) “His last word(s) were (was) ‘boobs.’  He’d like that.”
The problem is people have ‘last words’, not ‘a last word’ but Sam’s ‘last words’ were(was), in fact, A WORD. So #1 seems most grammatically accurate, yet #2 captures the feeling of the statement best. And #3 was just in my original script as I tried to walk the line between #1 and #2. And I am amused a little bit as #2 works a little better than it might purely because boobs are plural.  *shrug*
