Bob's heart arc

The arc about Bob's heart is the second story arc in The Petri Dish.

Plot
It begins with Bob watching The Wizard of Oz and then singing "If I Only Had a Heart" to Thaddeus Euphemism, who snaps at him to stop watching it and maintains that he is not giving Bob a heart.

In the next strip, Bob begs Thaddeus to give him a heart and Thaddeus reluctantly agrees but says that he'll give him "the same type of heart that the Wizard of Oz gave the Tin Man". He then asks if Bob knows what sort of heart that is and Bob responds in the negative. Thaddeus asks how Bob could not know what sort of heart the Wizard of Oz gave the Tin Man because Bob has seen the movie twenty times and Bob replies that he is too scared of the flying monkeys to watch past that point.

The story arc then concludes in the third strip with Thaddeus taking a fridge magnet shaped like a heart and putting it on Bob's chest while quoting from The Wizard of Oz. Bob is touched, which nauseates Thaddeus.

Trivia

 * This strip references The Wizard of Oz.
