Man, I love going over the cat with a flea comb and catching an especially big one. Like, a monster of a flea, so fat it's jammed between the tines of the comb and fighting to get out. You go to crush that fucker with your fingernail and you can hear an audible pop. If you're lucky, you get a nice shot of cat blood/flea guts splashing your face. That's just awesome.
