Use the /in (#sec).. I made a few funny ones... My favorite one is where my 3 druids argue over that I am not a bot. I have a few that go on for about 5 mins. To stop it I dont know how to do that Just dont hit the key :P
The /in command only works with stuff like /say /follow ect... cant cast spells or what not

Here is a 3 way conerstaion

(player1)
/say Hello player2 how is it going?
/in 7 /say Ehh its alright
/in 11 /say Shut up player3!
/in 15 /say Lets dance!
/in 17 /dance
(player2)
/in 3 /say Doing great player1!
/in 5 /So hows your day player1?
/in 12 /say Yeah Shut up!
/in 17 /dance
(player3)
/in 9 /say What about me you two? Don't want to talk to me?
/in 13 awww No one likes me
/in 17 /dance


Hope this helps! The convos just make you sound more like a bot and make people /tell spam you "reported" even more, its great!
