i [heart] my wife      &      
i [heart] spamtwo contending bumper stickers!
the first sticker sat directly inline with the driver of the early 1990's navy blue pickup truck; the second, directly in line with the passenger.
which begs the following questions:
is this an inside joke between the driver and the passenger?
is this a message of preferences for the person driving behind this vehicle?  as in driver: "i 
[heart] my wife"; and passenger (possibly the wife of driver): "i 
[heart] spam"?
or perhaps, because the driver 
[heart]'s his/her wife, he/she must also 
[heart] spam?  As in, I 
[heart] my wife, thus I 
must [heart] spam 
too because that's all she cooks?
or perhaps the driver 
[heart]'s both wife and spam?  Equally?
or possibly the original sticker was "i 
[heart] spam", placed there by the driver, then his/her wife made him/her rethink the original choice?
or maybe it's just your standard dysfunctional couple?
