Michael Palin says "something will happen" to celebrate Monty Python's 50th birthday - but marking a random year like 51.5 would be more appropriate.
The first episode of Monty Python's Flying Circus was broadcast in 1969.
Palin said: "There are plans being hatched to flog our wares - you don't miss an opportunity for an anniversary!"
But he said: "I feel celebrating a 50th is rather un-Python. We should be celebrating the 53rd or 51.5 year.
"We talk to each other. We have management in place who are sort of coming up with suggestions, so there will be things."
The troupe reunited for Monty Python Live (Mostly) in 2014.
