Homonyms Confuse Me Two (To? Too?)

Goddamn dandelions...

Dan and I were watching something on Discovery last night and a preview for this show came on.  

Dan: *glancing at the tv then looking back down at his laptop*  "Why would that show be on Discovery?"

Me:  "I dunno... why shouldn't it be?"  (I kind of copped a 'tude because I imagine myself to be more liberal than he is, even though neither one of us "partake" in the doobage.)

Dan:  "Who would watch a show about weeds?"

Me:

Dan:

Me:  "Weeds?"

Dan:  "Shouldn't that be on Home and Garden channel or whatever it's called?"

Me:  

Dan:

Me:  "Huh?"

Dan:  *laughing at his own wit*  "What do they do, have weed-pulling contests?  See who grows the best crab grass?"

Me:  "Honey... it's about the medical marijuana industry."

Dan:  

Me:  *snort*

Dan: *turning bright red*

Me:  *dying*

Dan's Vision:

Coming soon on Discovery... Weed Wars.
