Sex pills  

A kid was told to go to the pharmacy to get his father some heart pills. The entire time he was walking to it, he kept saying to himself "Heart pills, heart pills, can't forget the heart pills!" but he tripped over a rock and hit his head on the ground. When he got back up he said to himself "Wait.... what was i saying? oh now i remember! sex pills, sex pills, sex pills!" when he got to the pharmacy he walked up to the counter and said "i would like to buys some sex pills please."
the store clerk said "Who are they for?"
"my father"
"okay, tell him to take one pill every 24 hours."

After buying the sex pills he was walking home saying to himself "okay, one pill every 24 hours, one pill every 24 hours." but he tripped over the same rock and hit his head on the ground again. He got back up and said "Wait.... what was i saying? oh now i remember! 24 pills an hour, 24 pills an hour, 24 pills an hour."

The next day the kid went back to the pharmacy and said "i would like to return these sex pills please."
the store clerk was confused, so he said "Why do you want to return them?"

The kid crossed his arms and said "Well my mom's dead, my sister's pregnant, and now my dad's up on the roof saying 'here kitty kitty kitty'."

One of my friends told me this, if it's too adult oriented the mods can take it off.
