Morty there is no better time to make jokes, just as long as you keep your head in the game and you do not distract the rhythm of your co-patriots.
(This of course is an art, getting the timing right, no excess or deficiency, and thus we as the audience find it humorous when the timing is not quite perfect.)

I repeat what others have said, Sokka had a similar energy but his comedic timing was even worse than Bolin.
