Rudi is a German comic by Peter Puck. It tells about the life of Rudi and his buddy Freddy, their attempts to pick up women, parties in the scene and other hijinks.It started out as a comic strip in various magazines. The strips have been collected in several anthology comic books.Has a very good (German) homepage here.
Rudi and Freddy do this to visit a silvester party organized by a group of Straw Feminists. It doesn't end well.
Once, Rudi tried this trick to get backstage when his favorite band was in town. While the roadie/bouncer didn't seem to see through the disguise, he informed Rudi that a) the boys are all gay and b) he (Olaf, the bouncer) actually would be interested...
The Dominatrix: Rudi once wanted to go to the dentist and confused the door. They thought he wanted to do some dentist-themed roleplay. And afterwards, he gets Mistaken For Pervert.
In Vino Veritas: Some cute song birds start sieg-heiling, picking fights and generally acting like most obnoxious drunks after drinking beer.
It's a Costume Party, I Swear: Inverted. When he gets invited by the upper-class father of his girlfriend, he buys the most formal tailcoat he can get - only to see too late that all the fine folks are disguised as punks and skinheads. And his girlfriend calls him "impossible" for it.
Kavorka Man: Cousin Alfi is a kind of country bumpkin, but has success with the ladies. The fact that he saves one woman, White Knight-style, from a drug dealer who wants to cut up her face probably helped.
After being in a Goth disco, Freddy hits on an Italian girl (who was wearing black clothes, a hat with a veil and a big cross). Unfortunately she's the daughter of a mafia boss...
Also, in an early story: Freddy got his hands on a hippie and a skinhead costume and coerces Rudi to join him for a costume party. When Freddy drags Rudi along on the street, a group of (strangely, non-pacifist) hippies mistake them for a skinhead beating up a hippie and decide to teach the "skinhead" a lesson. And then, some real skinheads arrive at the scene...
Rape Is Funny If Male On Male: Rudi takes part in a workshop where people are supposed to get their problems solved via "sexperiences". Unfortunately for him, the teacher wants them to try same-sex ones.
Reincarnation: Rudi once gets hypno-treatment (from a quack) and "remembers" that his back pain comes from an earlier life when he was crucified at the same time/place as Jesus.
Once, a sleazy guy from the film business approached Rudi, suggesting him to become an actor, after which we see some Imagine Spots with Rudi as Rambo, Django, Humphrey Bogart in Casablanca, and James Bond. (Afterwards we find out that the films in question are porn, and Rudi isn't exactly happy about it.)
The Slacker: Heinz definitely; sometimes, Rudi and Freddy too.
Russian woman: "In 1997, I had anal sex with Bill Gates. Now I am pregnant..."
Subverted Trope: In one comic, several stereotypes get subverted. So we get a super-smart blonde hairdresser, a boring comic artist, a black guy who can't stand black music and has a short dick, and some sophisticated nazi skinheads who are totally aware that they only project their own deficits onto racial minorities.
Talking Animal: Apparently ants and slugs not only are this, but are also organized like a fascist state and actively planning to bring down human society. Especially, eat all their food. In other words, not only Humans Are Bastards in this comic.
Think Unsexy Thoughts: Rudi does this one time at a nude beach. Problem is that everything he tries to think of only makes him more horny. ("Square root of 4761 makes... 69! Shit, maths is too perverted!") Then, when he finally manages to get his Raging Stiffie under control (by thinking about cancer) - a pissed-of wasp stings him several times in a male body part, making things even worse.
