I heard this about two years ago, and I remebered now, what with this being Lent an' all...
So Jesus is on the cross, and he cries out, "Peter!"
"Yes Lord!", Peter said and tried to run up to Jesus, but the Roman soldiers stop him.
Jesus called out again, "Peter!"
"I'm coming Lord!", said Peter, and ran up, trying to dodge the Roman soldiers, but they managed to stop him.
Jesus called out for the third time. "Peter!"
"Yes Lord!", Peter shouted and doing stunts and acrobatics and what not, he finally reached the foot of the cross, all wounded and bleeding.
"You called and I am here, my master", Peter said.
"Peter", said the Lord."I can see your house from here".
