The greatest source for inspiration is the work or classroom environment. Where else is daydreaming the sole means of passing the time only for the most sensational ideas to erupt? Yes, you might burst into uncontrollable laughter while everyone else stares at your apparent psychotic outburst, or find yourself staying an hour late while still lost in reverie, but whatever you were thinking of was definitely better then what you should have been doing.
Based on a segment from the show Yes, Dear, here are "things I think about at work". Maybe if I'm lucky John Hiatt will make it into a song. 

-- Boobs. Greatest of God's inventions... or greatest cause for the wasting of future babies down a toilet?

-- How much longer can I justify watching The Hills because of "the hot girls"?

-- If the Apocalypse were to hit tomorrow will the X-Men have enough time to prepare?

-- If I lived in the 60's would I have been a Hippie, or just a regular guy with long hair doing LSD with five strangers I've been living with while quoting Jack Kerouac? 

-- What's cooler? Carlos Mencia stand up-athon or contracting chlamydia.

-- That girl has been staring at me all day; I think she's into me. I mean she is really cute but come on, I'm not a piece of meat.
 
-- The bathroom stall is the only place where I have seen a quote from Emerson signed by Lisa who apparently "gives great head." She also sucks, is gay, and was here. I called her phone number and wound up talking to my girlfriend for thirty minutes, weird...

-- Bathroom continued... Two streams: not better than one.

-- Why does every song from the 80's remind me of a David Copperfield show? Hmm if I were David Copperfield, where would I be? Down Niagara Falls with his career! Heyooo. (insert alternative illusion/career joke)

-- How much beer could a beerchuck chuck if a beerchuck could chuck beer?

-- Who would win in a fight? Bruce Lee or a hypersensitivity reaction to the muscle relaxant Equagesic. Too soon?

-- I think I'm going to start calling people from Maine, AniMAINEiacs. HAHA that's funny... right? No you're probably right that sucked. Oh no Tom caught me talking to myself; turn to side and pretend to have Bluetooth.

-- Second thought: I'm pretty sure that girl keeps looking at me because I have been intensely staring at her all day; I mean if I were Superman she'd be dead. She's now talking to my boss and pointing at me. Shit shit he's coming over jhdlkjdfhsdgu
