Is It Funny?

a pastor was minstering to a congregation on a miracle night, then a man who was said to be blind from bath was led forward and the pastor prayed for him, and after the prayer he said i can seeeeeeeeeeeeeeeeeeeee!!!!!!!!!!!!!!!!!!!!! , to confirm he could see the pastor brought a cloth before him and said , what colour is this cloth and in his excitement he said RED!!!!!!!
How did he know it was red, was he even blind?

my teacher once said that when blind people regain their sight, they can't recognize anything.

hmm thanks my younger brother cracked the joke at home, when i was relaxing after work so i thought it would be nice to bring it to us here, but it was really funny.

Thatz a good one.
