The band members are seen thrusting with no pants on, nudity is blurred.
In one episode, the band doesn't have any furniture, so they hire men to be couches and chairs and they sit on them and one guy says "And I keep finding coins in the cusions!" Later, another guy tells him (secretly in his ear so we cant hear it) where the coins actually came from, and the guy laughs and yells out "WHAT!?" and throws them down. (Meant for laughs).
In the episode "What happened" they see a woman giving labor to a child in their van, but it's nothing serious.
