Depends if im on the job, at home or somewhere like a friend or relatives house.
At work: Me and some of my co workers have this game we play. We make up puns through out the entire day to see which one of us will laugh at the others pun first loser has to pay up to whoever's pun he laughs at "5 bucks a round" Ex. Im a blacksmith and there's a guy that works with me he is both black and his name is smith. But we have to smith's of different race that work there so lets say someone says hey have you seen smith that works in the forge? I'd say oh are you referring to "Black Smith' and if that guy chuckles at the joke and is in the game he pays up to me. I know sounds pretty lame, but if your bored enough it's worth a few yucks.
At home: Im sure most of you are aware of the episode of family guy that I got this from. So one day Im driving down the street and I pass a shop and there is a guy unloading a massive speaker from the back of a large truck and I immediately hook a U and book it to that store thinking this is too good to be true. Any who long story I bought this massive speaker and set it in my living room it stands at a little over 7 ft in height and is fairly wide (maybe a little larger than a standard door) any who I've got a special scoop chair that I use only once on my most difficult of days for this one event. I have an old tape player that I managed to get along with the speaker and the tape i insert has nothing but smooth jazz and songs that include sooo much bass you can feel the air vibrate as it plays. I crank the stereo to the max lock the doors, cover the windows and go commando and play it. If you've ever watched a five gum commercial it was something like that. Initially I wanted to see if the blast from that speaker could push a glass back into my hand, like the episode of family guy. It didn't but every sound that comes from it makes all the air around my body vibrate and im sitting not 5 feet away from the speaker so its pretty entertaining or at least the feeling anyways.
At a friend or Relatives house: I get a few friends/family from the location im at or I can go it solo doesn't really matter. And I ride down the road a few times, windows down, blasting "What is love - Haddaway" And head bobbing NOT BANGING just a slight bob will do. and we ride past people just to see who's day we will brighten a bit. If seeing a car full of dudes riding down the street leaning out there windows head bobbing to what is love doesn't make you smile, relieve boredom or laugh nothing will.
