I have been on far too many courses in my working life.
It's almost compulsory to play 'Buzzword bingo' to alleviate the boredom. However, some colleagues and I have often played a game called 'Personal space invaders'. When you're on a course or at a seminar with staff from other organisations and there's the obligatory 'socialising/getting to know your fellow attendees' bollocks try this.
A specific target or goal (doorway, particular table/piece of carpet/whatever) is agreed upon by the players. Each player must pick a fellow attendee to use as a 'puck'. You then engage your 'puck' in conversation whist subtly invading their personal space in order for them to be manouvered into the 'goal'.
This is harder than it sounds as some people will find an excuse to leave the conversation as they are feeling uncomfortable (due to the 'invasion') some won't go where you want them to etc etc. The real skill is to keep up a conversation with someone who is slightly uncomfortable. Once the goal is reached the winning player must leap into the air yelling 'GOOOOOALL', pull their sweater/shirt over their face and run around waving his/her arms about in a Brazilian commentator styleee.
The most difficult 'pucks' in my experience have been women* (they think you're coming on to them) and gay men (same again).
Like I said - I've been on too many courses to take any of them seriously.

*However I have 'ahem' been propositioned by more than one lady due to this game,

If you do get propositioned during the course of the game,
I do hope that you see it through, and complete your awkward, sexual encounter by leaping into the air yelling 'GOOOOOALL', and run around waving your arms about in a Brazilian commentator styleee, at the point of orgasm.

Interesting idea!
If the opportunity arises in the future I shall give your suggestion a try.

We do this too
When someone really dull is droning on and on you manoeuvre them into being adjacent to a fellow player's conversation then say "Have you met David?", introduce them to eachother and disappear.

Oh dear
I would make the perfect puck for this. I have a friend who always stands ever so slightly close to me and she's been known to get me across a room as I take a step back to increase the distance to where it's comfortable for me, then she takes a step forward to decrease it to where it's comfortable for her, and so on. HAS SHE BEEN DOING THIS TO ME THE WHOLE TIME?!!!!
