Okay, here is another amusing (to me) tale:
Some GM's are very had core and insist that all characters start at 1st level, and this can be an issue if the group is very advanced. Also, training for levels usually happens "off screen" or via a "training montage".
So, in one game I was in, a first level character is added to a group of 6th-level, dual-classed characters in a AD&D (2nd ed) game. Rather than proceed on the planned adventure, the group decided to roam around and actively court
the wandering monster table. Whenever one (or more!) did show up, the group would hold back and keep a "safe corner" while the new character went out "alone" to deal with the monsters. Many of these encounters went much like the first...
New Character: "Umm... what are these monsters in front of me?"
Old Character 1: "Don't worry about that. Worry about holding your sword right! Pointy end towards the monster over there!"
Old Character 2: "Don't forget to follow through on each strike! Extend!"
[NC engages monster(s), gets reamed, and staggers back to the "corner"]
Old Character 3: "Ouch. That will leave a mark."
Old Character 4, to NC: "Watch carefully as I demonstrate parry kata #4"
[OC4 engages the monsters with only parries and non-damaging attacks, while the party cleric heals the NC]
OC1: "That's okay lad" (pantomimes brushing dust off the character),"You'll do better in round two"
OC2: "You need to change your grip. See, this is how you should be holding your sword" (pantomimes some grip changes and a 1-2-3 step attack)
NC: "Oh... now I see what you were saying! My foot should be turned inward! I got it now!"
OC1: "Alright, work on that this time and get back in there"
OC2: "Hey, OC4, let's let NC try a new attack routine on this monster"
[OC4 swaps out with NC]
[NC gets a few hits in...]
OC2: "Good shots lad. Now remember... "
[...NC gets eviscerated at this point. NC staggers back to the "corner", holding parts of himself in]
OC2: "Now, you over extended your lunge on that last strike, and this is what happens when you do that."
OC1: "Maybe you should try another line of work? Have you considered farming?"
NC: "No, I really like... (gurgles through sucking chest wound)... being a fighter. The army recruiter promised that the girls would be impressed...."
OC1: Throwing his hands up in the air, "I guess there is no help for it then."
[Party cleric heals NC]
OC2: "Once more into the breach..."
OC3, to OC2: "Are you from Britannia or something?"
...Rinse, lather, repeat... all night....
By the end of the night, the character was power-leveled to 6th level (single class), and much role-playing fun was had by all (though after that night, the GM did decide to relax his rule about 1st level characters only
