All the reasons David Banner turned into the Hulk. My favorites:
1. Problems with flat tire

24. Being tied up and fed soup by an elderly Japanese woman who doesn't understand words like "You've GOT to cut me loose!"
26. Falling through a rickety staircase while trying to get to the drunk girl who is about to jump off the roof, and then finding that she's locked the rooftop door
28. Being placed in a dumpster by the two garbagemen who think he's a thief, and who don't believe him when he says "Hey! There are rats in here!", and then being bitten by the rats to add injury to insult
29. Having two mean football players snap wet towels at him and shove him into the steam room which they have turned on to full blast
33. Yelled at by a mean cop, and then having mace sprayed in his face by same mean cop
34. Handcuffed to a woman who is falling over the cliff
36. Somehow running into a bear trap
38. Placed in a small room with a ravenous black panther
40. Falling into the churning water of a boathouse, and then inexplicably being repeatedly carried over the paddlewheel
42. Listening to ultrasonics
44. Kicking over a beehive and then being surprised when the bees are mad at him
47. Being stuck in a cab in New York rush hour traffic - "You don't understand, I have to be there by 4:00!" - "Hey, mac, it's rush hour, we ain't gettin' there til five, so relax." - "BUT I HAVE TO BE THERE BY FOUR!!!"
50. Receiving a speeding ticket
52. Locked in a drunk tank with a crazy person who insists he is Ernest Hemingway and then beats the stuffing out of David
56. Somehow getting himself into a bellfry and then realizing that a bell is there, just as it strikes the hour
68. Being placed in a cage with an angry gorilla
73. Being chained to a truck while his friend for the episode has been taken inside the trailer by the natives to be punished under the rites of La Culta de Cabeza Chocolata
75. Beaten up by all the other prisoners in the work camp, in the middle of the night while he is trying to sleep, when he emphatically told them not to beat him up that particular night
78. Being thrown under a New Orleans Mardi Gras parade float by a mean guy in a gorilla suit who gives David a few kicks for good measure
83. Being mistaken for mob boss Mike Cassidy, who looks exactly like him, and who everybody wants to beat up, so that David is repeatedly beaten up for no reason
89. Being trapped by McGee in a back room, and when he tries to run away, bashing his knee, crashing into a backboard, and doing generally klutzy things culminating with falling down the stairs and crashing into a giant flower pot
90. Being hit by a car and knocked twenty feet so that he tumbles down a conveniently open manhole
101. Punched out and thrown in the cactus bed so that David can thrash around on the cactus, even though he has plenty of avenues of escape
106. Being fed poisoned sushi
108. Having several clay pots broken over his head in the middle of the now-burning room (why is the room always burning?), and then knocking an entire case of same clay pots onto same head, and then, while lying very still and struggling not to get angry, having his pants catch fire
112. While paralyzed for the episode, somehow getting caught in the middle of a barroom brawl, and while trying to quietly wheel himself out of the room, being hit by a flying body and knocked down the stairs (what David is even doing in such a situation goes unexplained)
116. Somehow being caught under a rockslide, and then foolishly exposing one of his hands on the mountainside so that a big, heavy rock smashes it
