The host of the Friday night show will this week tackle complicated toys and unpredictable children on the annual seasonal programme.
Speaking to the RTE Guide, Ryan said that he has been offered a number of jumpers in the past few months, with some people offering to knit one in return for tickets.
"I was sent a box of Christmas jumpers by a young Irish firm, but we haven't decided yet," the presenter said.
"We're trying to decide if we want to go completely goofball with the jumpers, or avoid it and leave it in memory lane with Gay.
"I think we're veering towards a regular jumper.
"It's Gay's joke really and I think I should let him crack it, not me."
