God I went to the proctologist today and man, he wouldn't finish checking my ass for 6 hours already! What an asstronomer! Next time I go see a proctologist, I should ask him if he's gay or else if he is I won't let him examine my ass.

herbert was an avid asstronomer; he could determine the exact gravitational pull of an ass just by looking at it.

Da term "asstronomical cost" could refer to either a requested reimbursement dat is so "expensive" dat it actually includes intimacy with da recipient of whatever products and/or services dat he wishes to have supplied to him, or an absurdly-inflated "rate" dat someone charges for touchy-feely privileges of his booty.
