Bottoms up! Jimmy Fallon flaunts his delightful derriere as Joe Jonas gives him underwear modelling lesson
Usually it is the old man who passes along his wisdom to the younger.
But Joe Jonas mentored Jimmy Fallon on the finer points of underwear modelling as they hammed it up on the Tonight Show on Monday.
The dynamic duo each pulled on a pair of boxers over their trousers so they could partake in an hilarious pose down in front of the ebullient audience.

A pants story: Joe Jones and Jimmy Kimmel flaunted their delightful derrieres as they partook in a mock underwear modelling session on The Tonight Show on Monday
The nonsense began after Jimmy whipped out a photograph of the Jonas Brothers favourite reclining on a chair in just a pair of Guess pants.
Explaining the cringeworthy photograph, the 27-year-old DNCE frontman said: 'I'm trying to figure out why I did this one. Like, I'm just airing it out a little bit.'
Jimmy then magically produced a couple of pairs, and begged his guest to 'show me how it's done.'
The pair then stood virtually cheek to cheek as they playfully flaunted their pert posteriors, with the former SNL star's firm, yet pleasingly round, derriere undoubtedly stealing the show.

And as they worked the set, they then attempted to copy the Kleptomanic favourite's slouched chair pose.
Making a feeble attempt at a contemporaneous joke, Joe said, 'It's the Falcon fan losing pose,' referencing the Atlanta NFL side's embarrassing collapse in Sunday's Super Bowl.
Jimmy also quipped: 'Your basically saying that anyone could be a Guess model.'

He then managed to persuade Joe to recreate a cheesy side on pose.
Referencing their ridiculous outfits, the chat show host said: 'I can't even do that. I don't even want to. It's like wearing diapers.'
Jimmy also congratulated his guest, who performed his imaginatively titled tune Cake By The Ocean, on become the first ever men's underwear ambassador for Guess .
A prestigious appointment indeed, as even the most cynical of observers are sure to agree.
