I've been thinking about it, and it doesn't seem like such a great move to burn the way he did. Horse wasn't saying really anything too special, there wasn't much point in doing it to silence him. And it doesn't seem right to do it in response to Armadillo's dousing claim - at worst you expose a scum, and at best you expose part of the scum's role list.
And Joker must have decided to burn
after seeing Armadillo's claim (
#64): the host answered several mechanics questions in
#66, about 45 min after the claim. The Day Burn event (
#77) happened a while later. If the Joker had burned before seeing #64, the Day Event would have occurred sooner.
Theories why he would have done it anyway:
a) Joker was testing to see if Horse was a Beguiler
b) Joker wanted to see if his dousing target was night immune
c) Joker just wanted us to spend time talking about it
