I just read this about that series. I think that should tell you how silly it is.

In the second issue of the Doctor Who crossover comic Star Trek: The Next Generation - Doctor Who: Assimilation², the Enterprise’s holodecks received a systems upgrade and with it, a new Dixon Hill adventure, which Picard saved under “Picard Dixon Hill Seven”. The upgrades included new smells. Picard then invites Riker, Data and Dr. Crusher to test-run it for him where once inside, they head for a restaurant when they hear the TARDIS materializing and mistake it for a bug in the upgrade. In the restaurant, they meet the Eleventh Doctor and his companions Amy Pond and Rory Williams, who mistake the program to actually be 1940s San Francisco, while Riker, Data and Dr. Crusher mistake them to be holodeck characters and that the holodeck was malfunctioning again. Riker then ends the program and they’re surprised to see the TARDIS and its three occupants are still present.

Just the idea that the holodeck has ‘new smells.’ What?
